Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544828, here are decompositions:
- 79 + 31544749 = 31544828
- 109 + 31544719 = 31544828
- 241 + 31544587 = 31544828
- 277 + 31544551 = 31544828
- 457 + 31544371 = 31544828
- 547 + 31544281 = 31544828
- 607 + 31544221 = 31544828
- 661 + 31544167 = 31544828
Showing the first eight; more decompositions exist.
