Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1970, here are decompositions:
- 19 + 1951 = 1970
- 37 + 1933 = 1970
- 97 + 1873 = 1970
- 103 + 1867 = 1970
- 109 + 1861 = 1970
- 139 + 1831 = 1970
- 181 + 1789 = 1970
- 193 + 1777 = 1970
Showing the first eight; more decompositions exist.

The digit sequence 1970 first appears in π at position 3,525 of the decimal expansion (the 3,525ordinal-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.
