Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130650, here are decompositions:

7 + 130643 = 130650
11 + 130639 = 130650
17 + 130633 = 130650
19 + 130631 = 130650
29 + 130621 = 130650
31 + 130619 = 130650
61 + 130589 = 130650
71 + 130579 = 130650

Showing the first eight; more decompositions exist.
