Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621738, here are decompositions:

31 + 8621707 = 8621738
61 + 8621677 = 8621738
157 + 8621581 = 8621738
271 + 8621467 = 8621738
439 + 8621299 = 8621738
457 + 8621281 = 8621738
661 + 8621077 = 8621738
691 + 8621047 = 8621738

Showing the first eight; more decompositions exist.
