Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189928, here are decompositions:

  • 41 + 189887 = 189928
  • 47 + 189881 = 189928
  • 131 + 189797 = 189928
  • 227 + 189701 = 189928
  • 257 + 189671 = 189928
  • 311 + 189617 = 189928
  • 419 + 189509 = 189928
  • 449 + 189479 = 189928

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 189,928 and was likely granted around 1875.

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

Position in π

The digit sequence 189928 first appears in π at position 152,852 of the decimal expansion (the 152,852ordinal-suffix:nd 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.
