Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620862, here are decompositions:

139 + 8620723 = 8620862
199 + 8620663 = 8620862
223 + 8620639 = 8620862
241 + 8620621 = 8620862
433 + 8620429 = 8620862
631 + 8620231 = 8620862
643 + 8620219 = 8620862
673 + 8620189 = 8620862

Showing the first eight; more decompositions exist.
