Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115086, here are decompositions:

7 + 115079 = 115086
19 + 115067 = 115086
29 + 115057 = 115086
67 + 115019 = 115086
73 + 115013 = 115086
89 + 114997 = 115086
113 + 114973 = 115086
173 + 114913 = 115086

Showing the first eight; more decompositions exist.
