Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544774, here are decompositions:
- 3 + 31544771 = 31544774
- 61 + 31544713 = 31544774
- 223 + 31544551 = 31544774
- 241 + 31544533 = 31544774
- 463 + 31544311 = 31544774
- 607 + 31544167 = 31544774
- 643 + 31544131 = 31544774
- 733 + 31544041 = 31544774
Showing the first eight; more decompositions exist.
