Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534386, here are decompositions:
- 17 + 31534369 = 31534386
- 43 + 31534343 = 31534386
- 53 + 31534333 = 31534386
- 89 + 31534297 = 31534386
- 139 + 31534247 = 31534386
- 199 + 31534187 = 31534386
- 269 + 31534117 = 31534386
- 283 + 31534103 = 31534386
Showing the first eight; more decompositions exist.
