Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619418, here are decompositions:

149 + 8619269 = 8619418
251 + 8619167 = 8619418
317 + 8619101 = 8619418
347 + 8619071 = 8619418
359 + 8619059 = 8619418
419 + 8618999 = 8619418
557 + 8618861 = 8619418
659 + 8618759 = 8619418

Showing the first eight; more decompositions exist.
