Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580022, here are decompositions:

13 + 31580009 = 31580022
53 + 31579969 = 31580022
109 + 31579913 = 31580022
113 + 31579909 = 31580022
163 + 31579859 = 31580022
191 + 31579831 = 31580022
281 + 31579741 = 31580022
283 + 31579739 = 31580022

Showing the first eight; more decompositions exist.
