Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545682, here are decompositions:
- 41 + 31545641 = 31545682
- 53 + 31545629 = 31545682
- 59 + 31545623 = 31545682
- 71 + 31545611 = 31545682
- 83 + 31545599 = 31545682
- 281 + 31545401 = 31545682
- 353 + 31545329 = 31545682
- 359 + 31545323 = 31545682
Showing the first eight; more decompositions exist.
