Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588798, here are decompositions:

89 + 31588709 = 31588798
167 + 31588631 = 31588798
191 + 31588607 = 31588798
359 + 31588439 = 31588798
431 + 31588367 = 31588798
467 + 31588331 = 31588798
491 + 31588307 = 31588798
599 + 31588199 = 31588798

Showing the first eight; more decompositions exist.
