Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591092, here are decompositions:

31 + 31591061 = 31591092
61 + 31591031 = 31591092
79 + 31591013 = 31591092
83 + 31591009 = 31591092
101 + 31590991 = 31591092
149 + 31590943 = 31591092
151 + 31590941 = 31591092
163 + 31590929 = 31591092

Showing the first eight; more decompositions exist.
