Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606562, here are decompositions:

3 + 31606559 = 31606562
19 + 31606543 = 31606562
139 + 31606423 = 31606562
151 + 31606411 = 31606562
181 + 31606381 = 31606562
193 + 31606369 = 31606562
223 + 31606339 = 31606562
283 + 31606279 = 31606562

Showing the first eight; more decompositions exist.
