Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42218, here are decompositions:
- 31 + 42187 = 42218
- 37 + 42181 = 42218
- 61 + 42157 = 42218
- 79 + 42139 = 42218
- 157 + 42061 = 42218
- 199 + 42019 = 42218
- 271 + 41947 = 42218
- 277 + 41941 = 42218
Showing the first eight; more decompositions exist.
