Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2948, here are decompositions:
- 31 + 2917 = 2948
- 61 + 2887 = 2948
- 97 + 2851 = 2948
- 151 + 2797 = 2948
- 157 + 2791 = 2948
- 181 + 2767 = 2948
- 199 + 2749 = 2948
- 229 + 2719 = 2948
Showing the first eight; more decompositions exist.

The digit sequence 2948 first appears in π at position 186 of the decimal expansion (the 186ordinal-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.
