Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516506, here are decompositions:
- 5 + 31516501 = 31516506
- 13 + 31516493 = 31516506
- 23 + 31516483 = 31516506
- 37 + 31516469 = 31516506
- 79 + 31516427 = 31516506
- 83 + 31516423 = 31516506
- 127 + 31516379 = 31516506
- 149 + 31516357 = 31516506
Showing the first eight; more decompositions exist.
