Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130368, here are decompositions:

5 + 130363 = 130368
19 + 130349 = 130368
31 + 130337 = 130368
61 + 130307 = 130368
89 + 130279 = 130368
101 + 130267 = 130368
107 + 130261 = 130368
109 + 130259 = 130368

Showing the first eight; more decompositions exist.
