Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472626, here are decompositions:
- 29 + 472597 = 472626
- 53 + 472573 = 472626
- 67 + 472559 = 472626
- 83 + 472543 = 472626
- 103 + 472523 = 472626
- 149 + 472477 = 472626
- 157 + 472469 = 472626
- 227 + 472399 = 472626
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 472,626 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 472626 first appears in π at position 472,260 of the decimal expansion (the 472,260ordinal-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.
