Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179738, here are decompositions:

19 + 179719 = 179738
67 + 179671 = 179738
79 + 179659 = 179738
157 + 179581 = 179738
211 + 179527 = 179738
241 + 179497 = 179738
277 + 179461 = 179738
331 + 179407 = 179738

Showing the first eight; more decompositions exist.
