Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606532, here are decompositions:

3 + 31606529 = 31606532
103 + 31606429 = 31606532
109 + 31606423 = 31606532
151 + 31606381 = 31606532
163 + 31606369 = 31606532
193 + 31606339 = 31606532
271 + 31606261 = 31606532
619 + 31605913 = 31606532

Showing the first eight; more decompositions exist.
