Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2000, here are decompositions:
- 3 + 1997 = 2000
- 7 + 1993 = 2000
- 13 + 1987 = 2000
- 67 + 1933 = 2000
- 127 + 1873 = 2000
- 139 + 1861 = 2000
- 199 + 1801 = 2000
- 211 + 1789 = 2000
Showing the first eight; more decompositions exist.

The digit sequence 2000 first appears in π at position 600 of the decimal expansion (the 600ordinal-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.
