Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621372, here are decompositions:

73 + 8621299 = 8621372
163 + 8621209 = 8621372
229 + 8621143 = 8621372
271 + 8621101 = 8621372
283 + 8621089 = 8621372
379 + 8620993 = 8621372
421 + 8620951 = 8621372
499 + 8620873 = 8621372

Showing the first eight; more decompositions exist.
