Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591594, here are decompositions:

17 + 31591577 = 31591594
101 + 31591493 = 31591594
173 + 31591421 = 31591594
227 + 31591367 = 31591594
257 + 31591337 = 31591594
263 + 31591331 = 31591594
557 + 31591037 = 31591594
563 + 31591031 = 31591594

Showing the first eight; more decompositions exist.
