Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544874, here are decompositions:
- 17 + 31544857 = 31544874
- 47 + 31544827 = 31544874
- 103 + 31544771 = 31544874
- 157 + 31544717 = 31544874
- 313 + 31544561 = 31544874
- 331 + 31544543 = 31544874
- 457 + 31544417 = 31544874
- 503 + 31544371 = 31544874
Showing the first eight; more decompositions exist.
