Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123512, here are decompositions:

13 + 123499 = 123512
19 + 123493 = 123512
73 + 123439 = 123512
79 + 123433 = 123512
139 + 123373 = 123512
223 + 123289 = 123512
283 + 123229 = 123512
421 + 123091 = 123512

Showing the first eight; more decompositions exist.
