Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103438, here are decompositions:

  • 17 + 103421 = 103438
  • 29 + 103409 = 103438
  • 47 + 103391 = 103438
  • 89 + 103349 = 103438
  • 131 + 103307 = 103438
  • 149 + 103289 = 103438
  • 347 + 103091 = 103438
  • 359 + 103079 = 103438

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 103,438 and was likely granted around 1870.

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

Position in π

The digit sequence 103438 first appears in π at position 166,750 of the decimal expansion (the 166,750ordinal-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.
