Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591934, here are decompositions:

61 + 31591873 = 31591934
67 + 31591867 = 31591934
97 + 31591837 = 31591934
151 + 31591783 = 31591934
211 + 31591723 = 31591934
223 + 31591711 = 31591934
331 + 31591603 = 31591934
337 + 31591597 = 31591934

Showing the first eight; more decompositions exist.
