Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1948, here are decompositions:
- 17 + 1931 = 1948
- 41 + 1907 = 1948
- 47 + 1901 = 1948
- 59 + 1889 = 1948
- 71 + 1877 = 1948
- 101 + 1847 = 1948
- 137 + 1811 = 1948
- 227 + 1721 = 1948
Showing the first eight; more decompositions exist.

The digit sequence 1948 first appears in π at position 24,868 of the decimal expansion (the 24,868ordinal-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.
