Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154146, here are decompositions:

  • 19 + 154127 = 154146
  • 59 + 154087 = 154146
  • 67 + 154079 = 154146
  • 73 + 154073 = 154146
  • 79 + 154067 = 154146
  • 89 + 154057 = 154146
  • 103 + 154043 = 154146
  • 149 + 153997 = 154146

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 154,146 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 154146 first appears in π at position 136,545 of the decimal expansion (the 136,545ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
