Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621574, here are decompositions:

23 + 8621551 = 8621574
83 + 8621491 = 8621574
97 + 8621477 = 8621574
107 + 8621467 = 8621574
131 + 8621443 = 8621574
163 + 8621411 = 8621574
197 + 8621377 = 8621574
293 + 8621281 = 8621574

Showing the first eight; more decompositions exist.
