Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945402, here are decompositions:
- 5 + 945397 = 945402
- 11 + 945391 = 945402
- 13 + 945389 = 945402
- 43 + 945359 = 945402
- 53 + 945349 = 945402
- 61 + 945341 = 945402
- 71 + 945331 = 945402
- 109 + 945293 = 945402
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 945,402 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 945402 first appears in π at position 515,120 of the decimal expansion (the 515,120ordinal-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.
