Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152748, here are decompositions:

19 + 152729 = 152748
31 + 152717 = 152748
67 + 152681 = 152748
107 + 152641 = 152748
109 + 152639 = 152748
131 + 152617 = 152748
149 + 152599 = 152748
151 + 152597 = 152748

Showing the first eight; more decompositions exist.
