Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592162, here are decompositions:

3 + 31592159 = 31592162
13 + 31592149 = 31592162
109 + 31592053 = 31592162
163 + 31591999 = 31592162
379 + 31591783 = 31592162
439 + 31591723 = 31592162
709 + 31591453 = 31592162
991 + 31591171 = 31592162

Showing the first eight; more decompositions exist.
