Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621276, here are decompositions:

67 + 8621209 = 8621276
193 + 8621083 = 8621276
199 + 8621077 = 8621276
229 + 8621047 = 8621276
283 + 8620993 = 8621276
379 + 8620897 = 8621276
613 + 8620663 = 8621276
673 + 8620603 = 8621276

Showing the first eight; more decompositions exist.
