Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544990, here are decompositions:
- 67 + 31544923 = 31544990
- 163 + 31544827 = 31544990
- 241 + 31544749 = 31544990
- 271 + 31544719 = 31544990
- 277 + 31544713 = 31544990
- 439 + 31544551 = 31544990
- 457 + 31544533 = 31544990
- 619 + 31544371 = 31544990
Showing the first eight; more decompositions exist.
