Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594648, here are decompositions:

101 + 31594547 = 31594648
227 + 31594421 = 31594648
317 + 31594331 = 31594648
401 + 31594247 = 31594648
587 + 31594061 = 31594648
599 + 31594049 = 31594648
809 + 31593839 = 31594648
881 + 31593767 = 31594648

Showing the first eight; more decompositions exist.
