Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705426, here are decompositions:

7 + 8705419 = 8705426
43 + 8705383 = 8705426
127 + 8705299 = 8705426
157 + 8705269 = 8705426
277 + 8705149 = 8705426
349 + 8705077 = 8705426
397 + 8705029 = 8705426
523 + 8704903 = 8705426

Showing the first eight; more decompositions exist.
