Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621248, here are decompositions:

5 + 8621243 = 8621248
11 + 8621237 = 8621248
47 + 8621201 = 8621248
59 + 8621189 = 8621248
101 + 8621147 = 8621248
197 + 8621051 = 8621248
239 + 8621009 = 8621248
401 + 8620847 = 8621248

Showing the first eight; more decompositions exist.
