Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130672, here are decompositions:

23 + 130649 = 130672
29 + 130643 = 130672
41 + 130631 = 130672
53 + 130619 = 130672
83 + 130589 = 130672
149 + 130523 = 130672
233 + 130439 = 130672
263 + 130409 = 130672

Showing the first eight; more decompositions exist.
