Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12670, here are decompositions:
- 11 + 12659 = 12670
- 17 + 12653 = 12670
- 23 + 12647 = 12670
- 29 + 12641 = 12670
- 59 + 12611 = 12670
- 101 + 12569 = 12670
- 131 + 12539 = 12670
- 167 + 12503 = 12670
Showing the first eight; more decompositions exist.
