Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543458, here are decompositions:
- 5 + 31543453 = 31543458
- 7 + 31543451 = 31543458
- 29 + 31543429 = 31543458
- 61 + 31543397 = 31543458
- 97 + 31543361 = 31543458
- 109 + 31543349 = 31543458
- 127 + 31543331 = 31543458
- 157 + 31543301 = 31543458
Showing the first eight; more decompositions exist.
