Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42784, here are decompositions:
- 11 + 42773 = 42784
- 17 + 42767 = 42784
- 41 + 42743 = 42784
- 47 + 42737 = 42784
- 83 + 42701 = 42784
- 101 + 42683 = 42784
- 107 + 42677 = 42784
- 173 + 42611 = 42784
Showing the first eight; more decompositions exist.
