Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86938, here are decompositions:

11 + 86927 = 86938
101 + 86837 = 86938
167 + 86771 = 86938
227 + 86711 = 86938
311 + 86627 = 86938
359 + 86579 = 86938
461 + 86477 = 86938
557 + 86381 = 86938

Showing the first eight; more decompositions exist.
