Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63642, here are decompositions:
- 13 + 63629 = 63642
- 31 + 63611 = 63642
- 41 + 63601 = 63642
- 43 + 63599 = 63642
- 53 + 63589 = 63642
- 83 + 63559 = 63642
- 101 + 63541 = 63642
- 109 + 63533 = 63642
Showing the first eight; more decompositions exist.
