Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42798, here are decompositions:
- 5 + 42793 = 42798
- 11 + 42787 = 42798
- 31 + 42767 = 42798
- 47 + 42751 = 42798
- 61 + 42737 = 42798
- 71 + 42727 = 42798
- 79 + 42719 = 42798
- 89 + 42709 = 42798
Showing the first eight; more decompositions exist.
