Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78712, here are decompositions:

5 + 78707 = 78712
59 + 78653 = 78712
89 + 78623 = 78712
173 + 78539 = 78712
233 + 78479 = 78712
311 + 78401 = 78712
401 + 78311 = 78712
479 + 78233 = 78712

Showing the first eight; more decompositions exist.
