Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621076, here are decompositions:

29 + 8621047 = 8621076
59 + 8621017 = 8621076
67 + 8621009 = 8621076
83 + 8620993 = 8621076
103 + 8620973 = 8621076
127 + 8620949 = 8621076
179 + 8620897 = 8621076
229 + 8620847 = 8621076

Showing the first eight; more decompositions exist.
