Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137402, here are decompositions:
- 3 + 137399 = 137402
- 19 + 137383 = 137402
- 43 + 137359 = 137402
- 61 + 137341 = 137402
- 151 + 137251 = 137402
- 163 + 137239 = 137402
- 193 + 137209 = 137402
- 211 + 137191 = 137402
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 137,402 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 137402 first appears in π at position 667,938 of the decimal expansion (the 667,938ordinal-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.
