Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42792, here are decompositions:
- 5 + 42787 = 42792
- 19 + 42773 = 42792
- 41 + 42751 = 42792
- 73 + 42719 = 42792
- 83 + 42709 = 42792
- 89 + 42703 = 42792
- 103 + 42689 = 42792
- 109 + 42683 = 42792
Showing the first eight; more decompositions exist.
