Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544242, here are decompositions:
- 29 + 31544213 = 31544242
- 53 + 31544189 = 31544242
- 71 + 31544171 = 31544242
- 89 + 31544153 = 31544242
- 251 + 31543991 = 31544242
- 263 + 31543979 = 31544242
- 281 + 31543961 = 31544242
- 383 + 31543859 = 31544242
Showing the first eight; more decompositions exist.
