Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42646, here are decompositions:
- 3 + 42643 = 42646
- 5 + 42641 = 42646
- 89 + 42557 = 42646
- 113 + 42533 = 42646
- 137 + 42509 = 42646
- 173 + 42473 = 42646
- 179 + 42467 = 42646
- 239 + 42407 = 42646
Showing the first eight; more decompositions exist.
