Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507862, here are decompositions:
- 73 + 31507789 = 31507862
- 109 + 31507753 = 31507862
- 163 + 31507699 = 31507862
- 229 + 31507633 = 31507862
- 271 + 31507591 = 31507862
- 499 + 31507363 = 31507862
- 541 + 31507321 = 31507862
- 619 + 31507243 = 31507862
Showing the first eight; more decompositions exist.
