Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623738, here are decompositions:

17 + 8623721 = 8623738
59 + 8623679 = 8623738
191 + 8623547 = 8623738
419 + 8623319 = 8623738
491 + 8623247 = 8623738
677 + 8623061 = 8623738
701 + 8623037 = 8623738
719 + 8623019 = 8623738

Showing the first eight; more decompositions exist.
