Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619028, here are decompositions:

29 + 8618999 = 8619028
149 + 8618879 = 8619028
167 + 8618861 = 8619028
239 + 8618789 = 8619028
269 + 8618759 = 8619028
281 + 8618747 = 8619028
347 + 8618681 = 8619028
389 + 8618639 = 8619028

Showing the first eight; more decompositions exist.
