Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621262, here are decompositions:

19 + 8621243 = 8621262
53 + 8621209 = 8621262
61 + 8621201 = 8621262
73 + 8621189 = 8621262
79 + 8621183 = 8621262
109 + 8621153 = 8621262
173 + 8621089 = 8621262
179 + 8621083 = 8621262

Showing the first eight; more decompositions exist.
