Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42810, here are decompositions:
- 13 + 42797 = 42810
- 17 + 42793 = 42810
- 23 + 42787 = 42810
- 37 + 42773 = 42810
- 43 + 42767 = 42810
- 59 + 42751 = 42810
- 67 + 42743 = 42810
- 73 + 42737 = 42810
Showing the first eight; more decompositions exist.
