Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543838, here are decompositions:
- 61 + 31543777 = 31543838
- 127 + 31543711 = 31543838
- 307 + 31543531 = 31543838
- 349 + 31543489 = 31543838
- 409 + 31543429 = 31543838
- 607 + 31543231 = 31543838
- 619 + 31543219 = 31543838
- 631 + 31543207 = 31543838
Showing the first eight; more decompositions exist.
