Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544858, here are decompositions:
- 31 + 31544827 = 31544858
- 109 + 31544749 = 31544858
- 139 + 31544719 = 31544858
- 271 + 31544587 = 31544858
- 307 + 31544551 = 31544858
- 349 + 31544509 = 31544858
- 487 + 31544371 = 31544858
- 547 + 31544311 = 31544858
Showing the first eight; more decompositions exist.
