Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456846, here are decompositions:
- 17 + 31456829 = 31456846
- 59 + 31456787 = 31456846
- 107 + 31456739 = 31456846
- 167 + 31456679 = 31456846
- 257 + 31456589 = 31456846
- 359 + 31456487 = 31456846
- 467 + 31456379 = 31456846
- 569 + 31456277 = 31456846
Showing the first eight; more decompositions exist.
