Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627672, here are decompositions:

61 + 8627611 = 8627672
103 + 8627569 = 8627672
139 + 8627533 = 8627672
199 + 8627473 = 8627672
241 + 8627431 = 8627672
331 + 8627341 = 8627672
373 + 8627299 = 8627672
421 + 8627251 = 8627672

Showing the first eight; more decompositions exist.
