Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623722, here are decompositions:

5 + 8623717 = 8623722
43 + 8623679 = 8623722
61 + 8623661 = 8623722
71 + 8623651 = 8623722
83 + 8623639 = 8623722
101 + 8623621 = 8623722
103 + 8623619 = 8623722
139 + 8623583 = 8623722

Showing the first eight; more decompositions exist.
