Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42612, here are decompositions:
- 23 + 42589 = 42612
- 41 + 42571 = 42612
- 43 + 42569 = 42612
- 79 + 42533 = 42612
- 103 + 42509 = 42612
- 113 + 42499 = 42612
- 139 + 42473 = 42612
- 149 + 42463 = 42612
Showing the first eight; more decompositions exist.
