Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620426, here are decompositions:

137 + 8620289 = 8620426
149 + 8620277 = 8620426
167 + 8620259 = 8620426
239 + 8620187 = 8620426
293 + 8620133 = 8620426
317 + 8620109 = 8620426
383 + 8620043 = 8620426
557 + 8619869 = 8620426

Showing the first eight; more decompositions exist.
