Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130380, here are decompositions:

11 + 130369 = 130380
13 + 130367 = 130380
17 + 130363 = 130380
31 + 130349 = 130380
37 + 130343 = 130380
43 + 130337 = 130380
73 + 130307 = 130380
101 + 130279 = 130380

Showing the first eight; more decompositions exist.
