Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591796, here are decompositions:

3 + 31591793 = 31591796
13 + 31591783 = 31591796
73 + 31591723 = 31591796
109 + 31591687 = 31591796
193 + 31591603 = 31591796
199 + 31591597 = 31591796
283 + 31591513 = 31591796
349 + 31591447 = 31591796

Showing the first eight; more decompositions exist.
