Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152538, here are decompositions:

5 + 152533 = 152538
7 + 152531 = 152538
19 + 152519 = 152538
37 + 152501 = 152538
79 + 152459 = 152538
97 + 152441 = 152538
109 + 152429 = 152538
131 + 152407 = 152538

Showing the first eight; more decompositions exist.
