Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972644, here are decompositions:
- 7 + 972637 = 972644
- 31 + 972613 = 972644
- 67 + 972577 = 972644
- 151 + 972493 = 972644
- 163 + 972481 = 972644
- 241 + 972403 = 972644
- 271 + 972373 = 972644
- 307 + 972337 = 972644
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 972,644 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 972644 first appears in π at position 363,609 of the decimal expansion (the 363,609ordinal-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.
