Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623830, here are decompositions:

23 + 8623807 = 8623830
29 + 8623801 = 8623830
31 + 8623799 = 8623830
37 + 8623793 = 8623830
43 + 8623787 = 8623830
67 + 8623763 = 8623830
73 + 8623757 = 8623830
79 + 8623751 = 8623830

Showing the first eight; more decompositions exist.
