Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621748, here are decompositions:

41 + 8621707 = 8621748
67 + 8621681 = 8621748
71 + 8621677 = 8621748
131 + 8621617 = 8621748
139 + 8621609 = 8621748
167 + 8621581 = 8621748
197 + 8621551 = 8621748
257 + 8621491 = 8621748

Showing the first eight; more decompositions exist.
