Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152640, here are decompositions:

11 + 152629 = 152640
17 + 152623 = 152640
23 + 152617 = 152640
41 + 152599 = 152640
43 + 152597 = 152640
73 + 152567 = 152640
101 + 152539 = 152640
107 + 152533 = 152640

Showing the first eight; more decompositions exist.
