Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188670, here are decompositions:

17 + 188653 = 188670
37 + 188633 = 188670
61 + 188609 = 188670
67 + 188603 = 188670
107 + 188563 = 188670
137 + 188533 = 188670
151 + 188519 = 188670
179 + 188491 = 188670

Showing the first eight; more decompositions exist.
