Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596068, here are decompositions:

19 + 31596049 = 31596068
61 + 31596007 = 31596068
79 + 31595989 = 31596068
139 + 31595929 = 31596068
199 + 31595869 = 31596068
337 + 31595731 = 31596068
349 + 31595719 = 31596068
367 + 31595701 = 31596068

Showing the first eight; more decompositions exist.
