Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623578, here are decompositions:

31 + 8623547 = 8623578
59 + 8623519 = 8623578
149 + 8623429 = 8623578
239 + 8623339 = 8623578
317 + 8623261 = 8623578
331 + 8623247 = 8623578
541 + 8623037 = 8623578
547 + 8623031 = 8623578

Showing the first eight; more decompositions exist.
