Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539426, here are decompositions:
- 5 + 31539421 = 31539426
- 13 + 31539413 = 31539426
- 59 + 31539367 = 31539426
- 73 + 31539353 = 31539426
- 89 + 31539337 = 31539426
- 97 + 31539329 = 31539426
- 137 + 31539289 = 31539426
- 197 + 31539229 = 31539426
Showing the first eight; more decompositions exist.
