Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544672, here are decompositions:
- 139 + 31544533 = 31544672
- 163 + 31544509 = 31544672
- 349 + 31544323 = 31544672
- 541 + 31544131 = 31544672
- 619 + 31544053 = 31544672
- 631 + 31544041 = 31544672
- 661 + 31544011 = 31544672
- 769 + 31543903 = 31544672
Showing the first eight; more decompositions exist.
