Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588124, here are decompositions:

37 + 31588087 = 31588124
163 + 31587961 = 31588124
181 + 31587943 = 31588124
307 + 31587817 = 31588124
331 + 31587793 = 31588124
691 + 31587433 = 31588124
727 + 31587397 = 31588124
853 + 31587271 = 31588124

Showing the first eight; more decompositions exist.
