Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972624, here are decompositions:
- 11 + 972613 = 972624
- 13 + 972611 = 972624
- 43 + 972581 = 972624
- 47 + 972577 = 972624
- 67 + 972557 = 972624
- 131 + 972493 = 972624
- 151 + 972473 = 972624
- 181 + 972443 = 972624
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 972,624 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 972624 first appears in π at position 528,431 of the decimal expansion (the 528,431ordinal-suffix:st 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.
