Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606582, here are decompositions:

3 + 31606579 = 31606582
23 + 31606559 = 31606582
41 + 31606541 = 31606582
53 + 31606529 = 31606582
83 + 31606499 = 31606582
89 + 31606493 = 31606582
113 + 31606469 = 31606582
239 + 31606343 = 31606582

Showing the first eight; more decompositions exist.
