Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591214, here are decompositions:

7 + 31591207 = 31591214
37 + 31591177 = 31591214
43 + 31591171 = 31591214
73 + 31591141 = 31591214
223 + 31590991 = 31591214
271 + 31590943 = 31591214
283 + 31590931 = 31591214
307 + 31590907 = 31591214

Showing the first eight; more decompositions exist.
