Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179140, here are decompositions:

29 + 179111 = 179140
41 + 179099 = 179140
83 + 179057 = 179140
89 + 179051 = 179140
107 + 179033 = 179140
167 + 178973 = 179140
233 + 178907 = 179140
251 + 178889 = 179140

Showing the first eight; more decompositions exist.
