Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179720, here are decompositions:

3 + 179717 = 179720
31 + 179689 = 179720
61 + 179659 = 179720
97 + 179623 = 179720
127 + 179593 = 179720
139 + 179581 = 179720
157 + 179563 = 179720
193 + 179527 = 179720

Showing the first eight; more decompositions exist.
