Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628520, here are decompositions:

41 + 8628479 = 8628520
71 + 8628449 = 8628520
113 + 8628407 = 8628520
137 + 8628383 = 8628520
167 + 8628353 = 8628520
227 + 8628293 = 8628520
317 + 8628203 = 8628520
347 + 8628173 = 8628520

Showing the first eight; more decompositions exist.
