Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525616, here are decompositions:
- 7 + 31525609 = 31525616
- 13 + 31525603 = 31525616
- 79 + 31525537 = 31525616
- 127 + 31525489 = 31525616
- 139 + 31525477 = 31525616
- 337 + 31525279 = 31525616
- 349 + 31525267 = 31525616
- 373 + 31525243 = 31525616
Showing the first eight; more decompositions exist.
