Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591676, here are decompositions:

73 + 31591603 = 31591676
79 + 31591597 = 31591676
139 + 31591537 = 31591676
163 + 31591513 = 31591676
199 + 31591477 = 31591676
223 + 31591453 = 31591676
229 + 31591447 = 31591676
499 + 31591177 = 31591676

Showing the first eight; more decompositions exist.
