Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621352, here are decompositions:

13 + 8621339 = 8621352
43 + 8621309 = 8621352
53 + 8621299 = 8621352
71 + 8621281 = 8621352
109 + 8621243 = 8621352
139 + 8621213 = 8621352
151 + 8621201 = 8621352
163 + 8621189 = 8621352

Showing the first eight; more decompositions exist.
