Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648472, here are decompositions:

13 + 8648459 = 8648472
59 + 8648413 = 8648472
83 + 8648389 = 8648472
101 + 8648371 = 8648472
103 + 8648369 = 8648472
139 + 8648333 = 8648472
149 + 8648323 = 8648472
233 + 8648239 = 8648472

Showing the first eight; more decompositions exist.
