Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61570, here are decompositions:
- 11 + 61559 = 61570
- 17 + 61553 = 61570
- 23 + 61547 = 61570
- 59 + 61511 = 61570
- 83 + 61487 = 61570
- 101 + 61469 = 61570
- 107 + 61463 = 61570
- 167 + 61403 = 61570
Showing the first eight; more decompositions exist.
