Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615826, here are decompositions:
- 19 + 31615807 = 31615826
- 43 + 31615783 = 31615826
- 97 + 31615729 = 31615826
- 157 + 31615669 = 31615826
- 163 + 31615663 = 31615826
- 223 + 31615603 = 31615826
- 283 + 31615543 = 31615826
- 337 + 31615489 = 31615826
Showing the first eight; more decompositions exist.
