Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123758, here are decompositions:

31 + 123727 = 123758
97 + 123661 = 123758
127 + 123631 = 123758
139 + 123619 = 123758
157 + 123601 = 123758
211 + 123547 = 123758
241 + 123517 = 123758
331 + 123427 = 123758

Showing the first eight; more decompositions exist.
