Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645080, here are decompositions:

71 + 8645009 = 8645080
89 + 8644991 = 8645080
131 + 8644949 = 8645080
167 + 8644913 = 8645080
281 + 8644799 = 8645080
401 + 8644679 = 8645080
419 + 8644661 = 8645080
569 + 8644511 = 8645080

Showing the first eight; more decompositions exist.
