Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595736, here are decompositions:

5 + 31595731 = 31595736
13 + 31595723 = 31595736
17 + 31595719 = 31595736
19 + 31595717 = 31595736
79 + 31595657 = 31595736
83 + 31595653 = 31595736
163 + 31595573 = 31595736
167 + 31595569 = 31595736

Showing the first eight; more decompositions exist.
