Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588618, here are decompositions:

11 + 31588607 = 31588618
179 + 31588439 = 31588618
251 + 31588367 = 31588618
311 + 31588307 = 31588618
419 + 31588199 = 31588618
461 + 31588157 = 31588618
557 + 31588061 = 31588618
599 + 31588019 = 31588618

Showing the first eight; more decompositions exist.
