Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591314, here are decompositions:

23 + 31591291 = 31591314
107 + 31591207 = 31591314
127 + 31591187 = 31591314
137 + 31591177 = 31591314
173 + 31591141 = 31591314
277 + 31591037 = 31591314
283 + 31591031 = 31591314
373 + 31590941 = 31591314

Showing the first eight; more decompositions exist.
