Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606590, here are decompositions:

7 + 31606583 = 31606590
11 + 31606579 = 31606590
31 + 31606559 = 31606590
47 + 31606543 = 31606590
53 + 31606537 = 31606590
61 + 31606529 = 31606590
73 + 31606517 = 31606590
97 + 31606493 = 31606590

Showing the first eight; more decompositions exist.
