Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179780, here are decompositions:

31 + 179749 = 179780
37 + 179743 = 179780
43 + 179737 = 179780
61 + 179719 = 179780
109 + 179671 = 179780
157 + 179623 = 179780
199 + 179581 = 179780
283 + 179497 = 179780

Showing the first eight; more decompositions exist.
