Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42786, here are decompositions:
- 13 + 42773 = 42786
- 19 + 42767 = 42786
- 43 + 42743 = 42786
- 59 + 42727 = 42786
- 67 + 42719 = 42786
- 83 + 42703 = 42786
- 89 + 42697 = 42786
- 97 + 42689 = 42786
Showing the first eight; more decompositions exist.
