Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621236, here are decompositions:

23 + 8621213 = 8621236
47 + 8621189 = 8621236
53 + 8621183 = 8621236
83 + 8621153 = 8621236
89 + 8621147 = 8621236
149 + 8621087 = 8621236
227 + 8621009 = 8621236
263 + 8620973 = 8621236

Showing the first eight; more decompositions exist.
