Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6622, here are decompositions:

3 + 6619 = 6622
23 + 6599 = 6622
41 + 6581 = 6622
53 + 6569 = 6622
59 + 6563 = 6622
71 + 6551 = 6622
101 + 6521 = 6622
131 + 6491 = 6622

Showing the first eight; more decompositions exist.
