Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544664, here are decompositions:
- 7 + 31544657 = 31544664
- 103 + 31544561 = 31544664
- 113 + 31544551 = 31544664
- 131 + 31544533 = 31544664
- 271 + 31544393 = 31544664
- 293 + 31544371 = 31544664
- 317 + 31544347 = 31544664
- 353 + 31544311 = 31544664
Showing the first eight; more decompositions exist.
