Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621332, here are decompositions:

23 + 8621309 = 8621332
89 + 8621243 = 8621332
131 + 8621201 = 8621332
149 + 8621183 = 8621332
179 + 8621153 = 8621332
281 + 8621051 = 8621332
359 + 8620973 = 8621332
383 + 8620949 = 8621332

Showing the first eight; more decompositions exist.
