Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961530, here are decompositions:

19 + 961511 = 961530
23 + 961507 = 961530
43 + 961487 = 961530
71 + 961459 = 961530
79 + 961451 = 961530
83 + 961447 = 961530
103 + 961427 = 961530
131 + 961399 = 961530

Showing the first eight; more decompositions exist.
