Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623444, here are decompositions:

191 + 8623253 = 8623444
197 + 8623247 = 8623444
251 + 8623193 = 8623444
383 + 8623061 = 8623444
461 + 8622983 = 8623444
521 + 8622923 = 8623444
587 + 8622857 = 8623444
677 + 8622767 = 8623444

Showing the first eight; more decompositions exist.
