Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588126, here are decompositions:

23 + 31588103 = 31588126
107 + 31588019 = 31588126
233 + 31587893 = 31588126
347 + 31587779 = 31588126
359 + 31587767 = 31588126
389 + 31587737 = 31588126
419 + 31587707 = 31588126
467 + 31587659 = 31588126

Showing the first eight; more decompositions exist.
