Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606536, here are decompositions:

7 + 31606529 = 31606536
19 + 31606517 = 31606536
37 + 31606499 = 31606536
43 + 31606493 = 31606536
67 + 31606469 = 31606536
107 + 31606429 = 31606536
113 + 31606423 = 31606536
139 + 31606397 = 31606536

Showing the first eight; more decompositions exist.
