Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152780, here are decompositions:

3 + 152777 = 152780
13 + 152767 = 152780
109 + 152671 = 152780
139 + 152641 = 152780
151 + 152629 = 152780
157 + 152623 = 152780
163 + 152617 = 152780
181 + 152599 = 152780

Showing the first eight; more decompositions exist.
