Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179540, here are decompositions:

7 + 179533 = 179540
13 + 179527 = 179540
43 + 179497 = 179540
61 + 179479 = 179540
79 + 179461 = 179540
103 + 179437 = 179540
157 + 179383 = 179540
223 + 179317 = 179540

Showing the first eight; more decompositions exist.
