Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543710, here are decompositions:
- 13 + 31543697 = 31543710
- 19 + 31543691 = 31543710
- 41 + 31543669 = 31543710
- 67 + 31543643 = 31543710
- 131 + 31543579 = 31543710
- 139 + 31543571 = 31543710
- 167 + 31543543 = 31543710
- 179 + 31543531 = 31543710
Showing the first eight; more decompositions exist.
