Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542776, here are decompositions:
- 73 + 31542703 = 31542776
- 79 + 31542697 = 31542776
- 163 + 31542613 = 31542776
- 229 + 31542547 = 31542776
- 337 + 31542439 = 31542776
- 379 + 31542397 = 31542776
- 547 + 31542229 = 31542776
- 613 + 31542163 = 31542776
Showing the first eight; more decompositions exist.
