Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42662, here are decompositions:
- 13 + 42649 = 42662
- 19 + 42643 = 42662
- 73 + 42589 = 42662
- 163 + 42499 = 42662
- 199 + 42463 = 42662
- 211 + 42451 = 42662
- 229 + 42433 = 42662
- 271 + 42391 = 42662
Showing the first eight; more decompositions exist.
