Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971628, here are decompositions:
- 37 + 971591 = 971628
- 59 + 971569 = 971628
- 67 + 971561 = 971628
- 79 + 971549 = 971628
- 107 + 971521 = 971628
- 127 + 971501 = 971628
- 137 + 971491 = 971628
- 149 + 971479 = 971628
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 971,628 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 971628 first appears in π at position 242,300 of the decimal expansion (the 242,300ordinal-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.
