Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606482, here are decompositions:

13 + 31606469 = 31606482
53 + 31606429 = 31606482
59 + 31606423 = 31606482
71 + 31606411 = 31606482
101 + 31606381 = 31606482
109 + 31606373 = 31606482
113 + 31606369 = 31606482
139 + 31606343 = 31606482

Showing the first eight; more decompositions exist.
