Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495670, here are decompositions:
- 7 + 31495663 = 31495670
- 13 + 31495657 = 31495670
- 67 + 31495603 = 31495670
- 79 + 31495591 = 31495670
- 223 + 31495447 = 31495670
- 313 + 31495357 = 31495670
- 337 + 31495333 = 31495670
- 397 + 31495273 = 31495670
Showing the first eight; more decompositions exist.
