Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49218, here are decompositions:
- 7 + 49211 = 49218
- 11 + 49207 = 49218
- 17 + 49201 = 49218
- 19 + 49199 = 49218
- 41 + 49177 = 49218
- 47 + 49171 = 49218
- 61 + 49157 = 49218
- 79 + 49139 = 49218
Showing the first eight; more decompositions exist.
