Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588024, here are decompositions:

5 + 31588019 = 31588024
101 + 31587923 = 31588024
113 + 31587911 = 31588024
131 + 31587893 = 31588024
257 + 31587767 = 31588024
317 + 31587707 = 31588024
401 + 31587623 = 31588024
617 + 31587407 = 31588024

Showing the first eight; more decompositions exist.
