Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623558, here are decompositions:

11 + 8623547 = 8623558
29 + 8623529 = 8623558
149 + 8623409 = 8623558
239 + 8623319 = 8623558
311 + 8623247 = 8623558
491 + 8623067 = 8623558
521 + 8623037 = 8623558
599 + 8622959 = 8623558

Showing the first eight; more decompositions exist.
