Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123698, here are decompositions:

31 + 123667 = 123698
37 + 123661 = 123698
61 + 123637 = 123698
67 + 123631 = 123698
79 + 123619 = 123698
97 + 123601 = 123698
151 + 123547 = 123698
181 + 123517 = 123698

Showing the first eight; more decompositions exist.
