Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544590, here are decompositions:
- 3 + 31544587 = 31544590
- 17 + 31544573 = 31544590
- 29 + 31544561 = 31544590
- 47 + 31544543 = 31544590
- 59 + 31544531 = 31544590
- 173 + 31544417 = 31544590
- 197 + 31544393 = 31544590
- 227 + 31544363 = 31544590
Showing the first eight; more decompositions exist.
