Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1930, here are decompositions:
- 17 + 1913 = 1930
- 23 + 1907 = 1930
- 29 + 1901 = 1930
- 41 + 1889 = 1930
- 53 + 1877 = 1930
- 59 + 1871 = 1930
- 83 + 1847 = 1930
- 107 + 1823 = 1930
Showing the first eight; more decompositions exist.

The digit sequence 1930 first appears in π at position 3,030 of the decimal expansion (the 3,030ordinal-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.
