Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130536, here are decompositions:

5 + 130531 = 130536
13 + 130523 = 130536
19 + 130517 = 130536
23 + 130513 = 130536
47 + 130489 = 130536
53 + 130483 = 130536
59 + 130477 = 130536
67 + 130469 = 130536

Showing the first eight; more decompositions exist.
