Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543064, here are decompositions:
- 73 + 31542991 = 31543064
- 97 + 31542967 = 31543064
- 127 + 31542937 = 31543064
- 277 + 31542787 = 31543064
- 337 + 31542727 = 31543064
- 367 + 31542697 = 31543064
- 433 + 31542631 = 31543064
- 541 + 31542523 = 31543064
Showing the first eight; more decompositions exist.
