Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86936, here are decompositions:

7 + 86929 = 86936
13 + 86923 = 86936
67 + 86869 = 86936
79 + 86857 = 86936
193 + 86743 = 86936
307 + 86629 = 86936
337 + 86599 = 86936
349 + 86587 = 86936

Showing the first eight; more decompositions exist.
