Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978248, here are decompositions:
- 31 + 978217 = 978248
- 67 + 978181 = 978248
- 97 + 978151 = 978248
- 157 + 978091 = 978248
- 181 + 978067 = 978248
- 199 + 978049 = 978248
- 211 + 978037 = 978248
- 241 + 978007 = 978248
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 978,248 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 978248 first appears in π at position 253,194 of the decimal expansion (the 253,194ordinal-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.
