Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591334, here are decompositions:

3 + 31591331 = 31591334
43 + 31591291 = 31591334
127 + 31591207 = 31591334
157 + 31591177 = 31591334
163 + 31591171 = 31591334
193 + 31591141 = 31591334
241 + 31591093 = 31591334
457 + 31590877 = 31591334

Showing the first eight; more decompositions exist.
