Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115146, here are decompositions:

13 + 115133 = 115146
19 + 115127 = 115146
23 + 115123 = 115146
29 + 115117 = 115146
47 + 115099 = 115146
67 + 115079 = 115146
79 + 115067 = 115146
89 + 115057 = 115146

Showing the first eight; more decompositions exist.
