Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660722, here are decompositions:

23 + 8660699 = 8660722
29 + 8660693 = 8660722
41 + 8660681 = 8660722
113 + 8660609 = 8660722
179 + 8660543 = 8660722
353 + 8660369 = 8660722
383 + 8660339 = 8660722
431 + 8660291 = 8660722

Showing the first eight; more decompositions exist.
