Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591914, here are decompositions:

5 + 31591909 = 31591914
41 + 31591873 = 31591914
47 + 31591867 = 31591914
71 + 31591843 = 31591914
131 + 31591783 = 31591914
163 + 31591751 = 31591914
181 + 31591733 = 31591914
191 + 31591723 = 31591914

Showing the first eight; more decompositions exist.
