Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152530, here are decompositions:

11 + 152519 = 152530
29 + 152501 = 152530
71 + 152459 = 152530
89 + 152441 = 152530
101 + 152429 = 152530
107 + 152423 = 152530
113 + 152417 = 152530
137 + 152393 = 152530

Showing the first eight; more decompositions exist.
