Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641850, here are decompositions:

31 + 8641819 = 8641850
43 + 8641807 = 8641850
67 + 8641783 = 8641850
103 + 8641747 = 8641850
109 + 8641741 = 8641850
181 + 8641669 = 8641850
199 + 8641651 = 8641850
229 + 8641621 = 8641850

Showing the first eight; more decompositions exist.
