Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130426, here are decompositions:

3 + 130423 = 130426
17 + 130409 = 130426
47 + 130379 = 130426
59 + 130367 = 130426
83 + 130343 = 130426
89 + 130337 = 130426
167 + 130259 = 130426
173 + 130253 = 130426

Showing the first eight; more decompositions exist.
