Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671290, here are decompositions:

41 + 8671249 = 8671290
59 + 8671231 = 8671290
71 + 8671219 = 8671290
97 + 8671193 = 8671290
113 + 8671177 = 8671290
139 + 8671151 = 8671290
157 + 8671133 = 8671290
163 + 8671127 = 8671290

Showing the first eight; more decompositions exist.
