Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541296, here are decompositions:
- 29 + 31541267 = 31541296
- 53 + 31541243 = 31541296
- 167 + 31541129 = 31541296
- 179 + 31541117 = 31541296
- 257 + 31541039 = 31541296
- 317 + 31540979 = 31541296
- 509 + 31540787 = 31541296
- 569 + 31540727 = 31541296
Showing the first eight; more decompositions exist.
