Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541616, here are decompositions:
- 5 + 31541611 = 31541616
- 19 + 31541597 = 31541616
- 47 + 31541569 = 31541616
- 53 + 31541563 = 31541616
- 59 + 31541557 = 31541616
- 89 + 31541527 = 31541616
- 107 + 31541509 = 31541616
- 109 + 31541507 = 31541616
Showing the first eight; more decompositions exist.
