Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45218, here are decompositions:
- 37 + 45181 = 45218
- 79 + 45139 = 45218
- 97 + 45121 = 45218
- 157 + 45061 = 45218
- 211 + 45007 = 45218
- 331 + 44887 = 45218
- 367 + 44851 = 45218
- 379 + 44839 = 45218
Showing the first eight; more decompositions exist.
