Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152646, here are decompositions:

5 + 152641 = 152646
7 + 152639 = 152646
17 + 152629 = 152646
23 + 152623 = 152646
29 + 152617 = 152646
47 + 152599 = 152646
79 + 152567 = 152646
83 + 152563 = 152646

Showing the first eight; more decompositions exist.
