Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670426, here are decompositions:

19 + 8670407 = 8670426
29 + 8670397 = 8670426
53 + 8670373 = 8670426
73 + 8670353 = 8670426
113 + 8670313 = 8670426
229 + 8670197 = 8670426
269 + 8670157 = 8670426
337 + 8670089 = 8670426

Showing the first eight; more decompositions exist.
