Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179618, here are decompositions:

37 + 179581 = 179618
139 + 179479 = 179618
157 + 179461 = 179618
181 + 179437 = 179618
211 + 179407 = 179618
331 + 179287 = 179618
337 + 179281 = 179618
349 + 179269 = 179618

Showing the first eight; more decompositions exist.
