Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124218, here are decompositions:

5 + 124213 = 124218
19 + 124199 = 124218
37 + 124181 = 124218
47 + 124171 = 124218
71 + 124147 = 124218
79 + 124139 = 124218
97 + 124121 = 124218
131 + 124087 = 124218

Showing the first eight; more decompositions exist.
