Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591374, here are decompositions:

7 + 31591367 = 31591374
37 + 31591337 = 31591374
43 + 31591331 = 31591374
83 + 31591291 = 31591374
167 + 31591207 = 31591374
197 + 31591177 = 31591374
233 + 31591141 = 31591374
281 + 31591093 = 31591374

Showing the first eight; more decompositions exist.
