Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542624, here are decompositions:
- 11 + 31542613 = 31542624
- 37 + 31542587 = 31542624
- 101 + 31542523 = 31542624
- 137 + 31542487 = 31542624
- 167 + 31542457 = 31542624
- 227 + 31542397 = 31542624
- 233 + 31542391 = 31542624
- 251 + 31542373 = 31542624
Showing the first eight; more decompositions exist.
