Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42812, here are decompositions:
- 19 + 42793 = 42812
- 61 + 42751 = 42812
- 103 + 42709 = 42812
- 109 + 42703 = 42812
- 163 + 42649 = 42812
- 223 + 42589 = 42812
- 241 + 42571 = 42812
- 313 + 42499 = 42812
Showing the first eight; more decompositions exist.
