Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543500, here are decompositions:
- 11 + 31543489 = 31543500
- 19 + 31543481 = 31543500
- 47 + 31543453 = 31543500
- 71 + 31543429 = 31543500
- 103 + 31543397 = 31543500
- 139 + 31543361 = 31543500
- 151 + 31543349 = 31543500
- 199 + 31543301 = 31543500
Showing the first eight; more decompositions exist.
