Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130506, here are decompositions:

17 + 130489 = 130506
23 + 130483 = 130506
29 + 130477 = 130506
37 + 130469 = 130506
59 + 130447 = 130506
67 + 130439 = 130506
83 + 130423 = 130506
97 + 130409 = 130506

Showing the first eight; more decompositions exist.
