Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621506, here are decompositions:

29 + 8621477 = 8621506
53 + 8621453 = 8621506
167 + 8621339 = 8621506
197 + 8621309 = 8621506
263 + 8621243 = 8621506
269 + 8621237 = 8621506
293 + 8621213 = 8621506
317 + 8621189 = 8621506

Showing the first eight; more decompositions exist.
