Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543126, here are decompositions:
- 23 + 31543103 = 31543126
- 47 + 31543079 = 31543126
- 59 + 31543067 = 31543126
- 107 + 31543019 = 31543126
- 269 + 31542857 = 31543126
- 317 + 31542809 = 31543126
- 359 + 31542767 = 31543126
- 449 + 31542677 = 31543126
Showing the first eight; more decompositions exist.
