Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179988, here are decompositions:

7 + 179981 = 179988
19 + 179969 = 179988
31 + 179957 = 179988
37 + 179951 = 179988
41 + 179947 = 179988
71 + 179917 = 179988
79 + 179909 = 179988
89 + 179899 = 179988

Showing the first eight; more decompositions exist.
