Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182140, here are decompositions:

11 + 182129 = 182140
17 + 182123 = 182140
29 + 182111 = 182140
41 + 182099 = 182140
83 + 182057 = 182140
113 + 182027 = 182140
131 + 182009 = 182140
173 + 181967 = 182140

Showing the first eight; more decompositions exist.
