Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627490, here are decompositions:

17 + 8627473 = 8627490
23 + 8627467 = 8627490
43 + 8627447 = 8627490
59 + 8627431 = 8627490
61 + 8627429 = 8627490
73 + 8627417 = 8627490
127 + 8627363 = 8627490
139 + 8627351 = 8627490

Showing the first eight; more decompositions exist.
