Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179190, here are decompositions:

17 + 179173 = 179190
23 + 179167 = 179190
29 + 179161 = 179190
47 + 179143 = 179190
71 + 179119 = 179190
79 + 179111 = 179190
83 + 179107 = 179190
101 + 179089 = 179190

Showing the first eight; more decompositions exist.
