Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651722, here are decompositions:

5 + 8651717 = 8651722
11 + 8651711 = 8651722
29 + 8651693 = 8651722
59 + 8651663 = 8651722
83 + 8651639 = 8651722
113 + 8651609 = 8651722
173 + 8651549 = 8651722
179 + 8651543 = 8651722

Showing the first eight; more decompositions exist.
