Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591678, here are decompositions:

61 + 8591617 = 8591678
79 + 8591599 = 8591678
211 + 8591467 = 8591678
229 + 8591449 = 8591678
367 + 8591311 = 8591678
379 + 8591299 = 8591678
421 + 8591257 = 8591678
547 + 8591131 = 8591678

Showing the first eight; more decompositions exist.
