Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606620, here are decompositions:

37 + 31606583 = 31606620
41 + 31606579 = 31606620
61 + 31606559 = 31606620
79 + 31606541 = 31606620
83 + 31606537 = 31606620
103 + 31606517 = 31606620
127 + 31606493 = 31606620
151 + 31606469 = 31606620

Showing the first eight; more decompositions exist.
