Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185152, here are decompositions:

3 + 185149 = 185152
29 + 185123 = 185152
53 + 185099 = 185152
83 + 185069 = 185152
89 + 185063 = 185152
101 + 185051 = 185152
131 + 185021 = 185152
239 + 184913 = 185152

Showing the first eight; more decompositions exist.
