Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978672, here are decompositions:
- 29 + 978643 = 978672
- 53 + 978619 = 978672
- 61 + 978611 = 978672
- 73 + 978599 = 978672
- 103 + 978569 = 978672
- 131 + 978541 = 978672
- 151 + 978521 = 978672
- 181 + 978491 = 978672
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 978,672 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 978672 first appears in π at position 548,170 of the decimal expansion (the 548,170ordinal-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.
