Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739426, here are decompositions:

29 + 8739397 = 8739426
37 + 8739389 = 8739426
67 + 8739359 = 8739426
89 + 8739337 = 8739426
127 + 8739299 = 8739426
229 + 8739197 = 8739426
233 + 8739193 = 8739426
239 + 8739187 = 8739426

Showing the first eight; more decompositions exist.
