Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124278, here are decompositions:

29 + 124249 = 124278
31 + 124247 = 124278
47 + 124231 = 124278
79 + 124199 = 124278
97 + 124181 = 124278
107 + 124171 = 124278
131 + 124147 = 124278
139 + 124139 = 124278

Showing the first eight; more decompositions exist.
