Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621524, here are decompositions:

47 + 8621477 = 8621524
71 + 8621453 = 8621524
113 + 8621411 = 8621524
281 + 8621243 = 8621524
311 + 8621213 = 8621524
677 + 8620847 = 8621524
683 + 8620841 = 8621524
797 + 8620727 = 8621524

Showing the first eight; more decompositions exist.
