Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61564, here are decompositions:
- 3 + 61561 = 61564
- 5 + 61559 = 61564
- 11 + 61553 = 61564
- 17 + 61547 = 61564
- 53 + 61511 = 61564
- 71 + 61493 = 61564
- 101 + 61463 = 61564
- 233 + 61331 = 61564
Showing the first eight; more decompositions exist.
