Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545744, here are decompositions:
- 5 + 31545739 = 31545744
- 7 + 31545737 = 31545744
- 31 + 31545713 = 31545744
- 103 + 31545641 = 31545744
- 137 + 31545607 = 31545744
- 257 + 31545487 = 31545744
- 337 + 31545407 = 31545744
- 353 + 31545391 = 31545744
Showing the first eight; more decompositions exist.
