Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179666, here are decompositions:

7 + 179659 = 179666
43 + 179623 = 179666
73 + 179593 = 179666
103 + 179563 = 179666
139 + 179527 = 179666
229 + 179437 = 179666
283 + 179383 = 179666
349 + 179317 = 179666

Showing the first eight; more decompositions exist.
