Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623620, here are decompositions:

17 + 8623603 = 8623620
37 + 8623583 = 8623620
41 + 8623579 = 8623620
73 + 8623547 = 8623620
97 + 8623523 = 8623620
101 + 8623519 = 8623620
191 + 8623429 = 8623620
197 + 8623423 = 8623620

Showing the first eight; more decompositions exist.
