Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86942, here are decompositions:

3 + 86939 = 86942
13 + 86929 = 86942
19 + 86923 = 86942
73 + 86869 = 86942
199 + 86743 = 86942
223 + 86719 = 86942
313 + 86629 = 86942
409 + 86533 = 86942

Showing the first eight; more decompositions exist.
