Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42146, here are decompositions:
- 7 + 42139 = 42146
- 73 + 42073 = 42146
- 103 + 42043 = 42146
- 127 + 42019 = 42146
- 163 + 41983 = 42146
- 193 + 41953 = 42146
- 199 + 41947 = 42146
- 283 + 41863 = 42146
Showing the first eight; more decompositions exist.
