Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153530, here are decompositions:

7 + 153523 = 153530
19 + 153511 = 153530
31 + 153499 = 153530
43 + 153487 = 153530
61 + 153469 = 153530
73 + 153457 = 153530
103 + 153427 = 153530
109 + 153421 = 153530

Showing the first eight; more decompositions exist.
