Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588136, here are decompositions:

7 + 31588129 = 31588136
157 + 31587979 = 31588136
193 + 31587943 = 31588136
277 + 31587859 = 31588136
337 + 31587799 = 31588136
439 + 31587697 = 31588136
709 + 31587427 = 31588136
739 + 31587397 = 31588136

Showing the first eight; more decompositions exist.
