Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42826, here are decompositions:
- 5 + 42821 = 42826
- 29 + 42797 = 42826
- 53 + 42773 = 42826
- 59 + 42767 = 42826
- 83 + 42743 = 42826
- 89 + 42737 = 42826
- 107 + 42719 = 42826
- 137 + 42689 = 42826
Showing the first eight; more decompositions exist.
