Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130678, here are decompositions:

29 + 130649 = 130678
47 + 130631 = 130678
59 + 130619 = 130678
89 + 130589 = 130678
131 + 130547 = 130678
239 + 130439 = 130678
269 + 130409 = 130678
311 + 130367 = 130678

Showing the first eight; more decompositions exist.
