Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545124, here are decompositions:
- 5 + 31545119 = 31545124
- 41 + 31545083 = 31545124
- 101 + 31545023 = 31545124
- 353 + 31544771 = 31545124
- 467 + 31544657 = 31545124
- 563 + 31544561 = 31545124
- 593 + 31544531 = 31545124
- 761 + 31544363 = 31545124
Showing the first eight; more decompositions exist.
