Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123618, here are decompositions:

17 + 123601 = 123618
37 + 123581 = 123618
67 + 123551 = 123618
71 + 123547 = 123618
101 + 123517 = 123618
127 + 123491 = 123618
139 + 123479 = 123618
179 + 123439 = 123618

Showing the first eight; more decompositions exist.
