Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516622, here are decompositions:

3 + 31516619 = 31516622
19 + 31516603 = 31516622
79 + 31516543 = 31516622
103 + 31516519 = 31516622
139 + 31516483 = 31516622
199 + 31516423 = 31516622
211 + 31516411 = 31516622
421 + 31516201 = 31516622

Showing the first eight; more decompositions exist.
