Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648288, here are decompositions:

37 + 8648251 = 8648288
67 + 8648221 = 8648288
97 + 8648191 = 8648288
109 + 8648179 = 8648288
139 + 8648149 = 8648288
157 + 8648131 = 8648288
409 + 8647879 = 8648288
487 + 8647801 = 8648288

Showing the first eight; more decompositions exist.
