Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544972, here are decompositions:
- 3 + 31544969 = 31544972
- 31 + 31544941 = 31544972
- 73 + 31544899 = 31544972
- 223 + 31544749 = 31544972
- 421 + 31544551 = 31544972
- 439 + 31544533 = 31544972
- 463 + 31544509 = 31544972
- 601 + 31544371 = 31544972
Showing the first eight; more decompositions exist.
