Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591062, here are decompositions:

31 + 31591031 = 31591062
53 + 31591009 = 31591062
71 + 31590991 = 31591062
103 + 31590959 = 31591062
131 + 31590931 = 31591062
163 + 31590899 = 31591062
229 + 31590833 = 31591062
271 + 31590791 = 31591062

Showing the first eight; more decompositions exist.
