Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2572, here are decompositions:
- 23 + 2549 = 2572
- 29 + 2543 = 2572
- 41 + 2531 = 2572
- 113 + 2459 = 2572
- 131 + 2441 = 2572
- 149 + 2423 = 2572
- 173 + 2399 = 2572
- 179 + 2393 = 2572
Showing the first eight; more decompositions exist.

The digit sequence 2572 first appears in π at position 1,006 of the decimal expansion (the 1,006ordinal-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.
