Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623408, here are decompositions:

89 + 8623319 = 8623408
347 + 8623061 = 8623408
389 + 8623019 = 8623408
449 + 8622959 = 8623408
641 + 8622767 = 8623408
701 + 8622707 = 8623408
797 + 8622611 = 8623408
887 + 8622521 = 8623408

Showing the first eight; more decompositions exist.
