Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151530, here are decompositions:

7 + 151523 = 151530
13 + 151517 = 151530
23 + 151507 = 151530
31 + 151499 = 151530
47 + 151483 = 151530
53 + 151477 = 151530
59 + 151471 = 151530
79 + 151451 = 151530

Showing the first eight; more decompositions exist.
