Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606600, here are decompositions:

17 + 31606583 = 31606600
41 + 31606559 = 31606600
59 + 31606541 = 31606600
71 + 31606529 = 31606600
83 + 31606517 = 31606600
101 + 31606499 = 31606600
107 + 31606493 = 31606600
131 + 31606469 = 31606600

Showing the first eight; more decompositions exist.
