Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15670, here are decompositions:
- 3 + 15667 = 15670
- 23 + 15647 = 15670
- 29 + 15641 = 15670
- 41 + 15629 = 15670
- 89 + 15581 = 15670
- 101 + 15569 = 15670
- 173 + 15497 = 15670
- 197 + 15473 = 15670
Showing the first eight; more decompositions exist.
