Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671390, here are decompositions:

23 + 8671367 = 8671390
29 + 8671361 = 8671390
59 + 8671331 = 8671390
83 + 8671307 = 8671390
197 + 8671193 = 8671390
239 + 8671151 = 8671390
257 + 8671133 = 8671390
263 + 8671127 = 8671390

Showing the first eight; more decompositions exist.
