Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674390, here are decompositions:

29 + 8674361 = 8674390
41 + 8674349 = 8674390
47 + 8674343 = 8674390
59 + 8674331 = 8674390
83 + 8674307 = 8674390
281 + 8674109 = 8674390
353 + 8674037 = 8674390
401 + 8673989 = 8674390

Showing the first eight; more decompositions exist.
