Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42912, here are decompositions:
- 11 + 42901 = 42912
- 13 + 42899 = 42912
- 53 + 42859 = 42912
- 59 + 42853 = 42912
- 71 + 42841 = 42912
- 73 + 42839 = 42912
- 83 + 42829 = 42912
- 139 + 42773 = 42912
Showing the first eight; more decompositions exist.
