Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121402, here are decompositions:
- 23 + 121379 = 121402
- 53 + 121349 = 121402
- 59 + 121343 = 121402
- 89 + 121313 = 121402
- 131 + 121271 = 121402
- 173 + 121229 = 121402
- 233 + 121169 = 121402
- 251 + 121151 = 121402
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 121,402 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 121402 first appears in π at position 124,115 of the decimal expansion (the 124,115ordinal-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.
