Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42860, here are decompositions:
- 7 + 42853 = 42860
- 19 + 42841 = 42860
- 31 + 42829 = 42860
- 67 + 42793 = 42860
- 73 + 42787 = 42860
- 109 + 42751 = 42860
- 151 + 42709 = 42860
- 157 + 42703 = 42860
Showing the first eight; more decompositions exist.
