Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539452, here are decompositions:
- 13 + 31539439 = 31539452
- 31 + 31539421 = 31539452
- 103 + 31539349 = 31539452
- 163 + 31539289 = 31539452
- 181 + 31539271 = 31539452
- 211 + 31539241 = 31539452
- 223 + 31539229 = 31539452
- 379 + 31539073 = 31539452
Showing the first eight; more decompositions exist.
