Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123782, here are decompositions:

151 + 123631 = 123782
163 + 123619 = 123782
181 + 123601 = 123782
199 + 123583 = 123782
229 + 123553 = 123782
283 + 123499 = 123782
349 + 123433 = 123782
409 + 123373 = 123782

Showing the first eight; more decompositions exist.
