Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543728, here are decompositions:
- 5 + 31543723 = 31543728
- 17 + 31543711 = 31543728
- 31 + 31543697 = 31543728
- 37 + 31543691 = 31543728
- 59 + 31543669 = 31543728
- 67 + 31543661 = 31543728
- 149 + 31543579 = 31543728
- 157 + 31543571 = 31543728
Showing the first eight; more decompositions exist.
