Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131622, here are decompositions:

5 + 131617 = 131622
11 + 131611 = 131622
31 + 131591 = 131622
41 + 131581 = 131622
61 + 131561 = 131622
79 + 131543 = 131622
103 + 131519 = 131622
173 + 131449 = 131622

Showing the first eight; more decompositions exist.
