Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588652, here are decompositions:

181 + 31588471 = 31588652
211 + 31588441 = 31588652
283 + 31588369 = 31588652
331 + 31588321 = 31588652
349 + 31588303 = 31588652
523 + 31588129 = 31588652
673 + 31587979 = 31588652
691 + 31587961 = 31588652

Showing the first eight; more decompositions exist.
