Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179642, here are decompositions:

19 + 179623 = 179642
61 + 179581 = 179642
79 + 179563 = 179642
109 + 179533 = 179642
163 + 179479 = 179642
181 + 179461 = 179642
373 + 179269 = 179642
409 + 179233 = 179642

Showing the first eight; more decompositions exist.
