Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623906, here are decompositions:

3 + 8623903 = 8623906
23 + 8623883 = 8623906
59 + 8623847 = 8623906
107 + 8623799 = 8623906
113 + 8623793 = 8623906
149 + 8623757 = 8623906
227 + 8623679 = 8623906
359 + 8623547 = 8623906

Showing the first eight; more decompositions exist.
