Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621584, here are decompositions:

3 + 8621581 = 8621584
107 + 8621477 = 8621584
131 + 8621453 = 8621584
173 + 8621411 = 8621584
347 + 8621237 = 8621584
383 + 8621201 = 8621584
401 + 8621183 = 8621584
431 + 8621153 = 8621584

Showing the first eight; more decompositions exist.
