Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543776, here are decompositions:
- 7 + 31543769 = 31543776
- 13 + 31543763 = 31543776
- 53 + 31543723 = 31543776
- 79 + 31543697 = 31543776
- 107 + 31543669 = 31543776
- 197 + 31543579 = 31543776
- 233 + 31543543 = 31543776
- 347 + 31543429 = 31543776
Showing the first eight; more decompositions exist.
