Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12790, here are decompositions:
- 47 + 12743 = 12790
- 101 + 12689 = 12790
- 131 + 12659 = 12790
- 137 + 12653 = 12790
- 149 + 12641 = 12790
- 179 + 12611 = 12790
- 251 + 12539 = 12790
- 263 + 12527 = 12790
Showing the first eight; more decompositions exist.
