Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606662, here are decompositions:

5 + 31606657 = 31606662
11 + 31606651 = 31606662
19 + 31606643 = 31606662
79 + 31606583 = 31606662
83 + 31606579 = 31606662
103 + 31606559 = 31606662
163 + 31606499 = 31606662
193 + 31606469 = 31606662

Showing the first eight; more decompositions exist.
