Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486796, here are decompositions:
- 73 + 31486723 = 31486796
- 139 + 31486657 = 31486796
- 157 + 31486639 = 31486796
- 163 + 31486633 = 31486796
- 193 + 31486603 = 31486796
- 373 + 31486423 = 31486796
- 379 + 31486417 = 31486796
- 409 + 31486387 = 31486796
Showing the first eight; more decompositions exist.
