Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42900, here are decompositions:
- 37 + 42863 = 42900
- 41 + 42859 = 42900
- 47 + 42853 = 42900
- 59 + 42841 = 42900
- 61 + 42839 = 42900
- 71 + 42829 = 42900
- 79 + 42821 = 42900
- 103 + 42797 = 42900
Showing the first eight; more decompositions exist.
