Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535426, here are decompositions:
- 3 + 31535423 = 31535426
- 7 + 31535419 = 31535426
- 163 + 31535263 = 31535426
- 193 + 31535233 = 31535426
- 199 + 31535227 = 31535426
- 283 + 31535143 = 31535426
- 313 + 31535113 = 31535426
- 367 + 31535059 = 31535426
Showing the first eight; more decompositions exist.
