Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615742, here are decompositions:
- 13 + 31615729 = 31615742
- 31 + 31615711 = 31615742
- 73 + 31615669 = 31615742
- 79 + 31615663 = 31615742
- 139 + 31615603 = 31615742
- 199 + 31615543 = 31615742
- 271 + 31615471 = 31615742
- 313 + 31615429 = 31615742
Showing the first eight; more decompositions exist.
