Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048, here are decompositions:
- 17 + 1031 = 1048
- 29 + 1019 = 1048
- 71 + 977 = 1048
- 101 + 947 = 1048
- 107 + 941 = 1048
- 137 + 911 = 1048
- 167 + 881 = 1048
- 191 + 857 = 1048
Showing the first eight; more decompositions exist.

The digit sequence 1048 first appears in π at position 2,874 of the decimal expansion (the 2,874ordinal-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.
