Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588196, here are decompositions:

67 + 31588129 = 31588196
109 + 31588087 = 31588196
193 + 31588003 = 31588196
337 + 31587859 = 31588196
379 + 31587817 = 31588196
397 + 31587799 = 31588196
499 + 31587697 = 31588196
769 + 31587427 = 31588196

Showing the first eight; more decompositions exist.
