Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543754, here are decompositions:
- 3 + 31543751 = 31543754
- 31 + 31543723 = 31543754
- 43 + 31543711 = 31543754
- 211 + 31543543 = 31543754
- 223 + 31543531 = 31543754
- 523 + 31543231 = 31543754
- 547 + 31543207 = 31543754
- 787 + 31542967 = 31543754
Showing the first eight; more decompositions exist.
