Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2070, here are decompositions:
- 7 + 2063 = 2070
- 17 + 2053 = 2070
- 31 + 2039 = 2070
- 41 + 2029 = 2070
- 43 + 2027 = 2070
- 53 + 2017 = 2070
- 59 + 2011 = 2070
- 67 + 2003 = 2070
Showing the first eight; more decompositions exist.

The digit sequence 2070 first appears in π at position 15,776 of the decimal expansion (the 15,776ordinal-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.
