Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115182, here are decompositions:

19 + 115163 = 115182
29 + 115153 = 115182
31 + 115151 = 115182
59 + 115123 = 115182
83 + 115099 = 115182
103 + 115079 = 115182
163 + 115019 = 115182
181 + 115001 = 115182

Showing the first eight; more decompositions exist.
