Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594484, here are decompositions:

151 + 31594333 = 31594484
211 + 31594273 = 31594484
421 + 31594063 = 31594484
541 + 31593943 = 31594484
547 + 31593937 = 31594484
853 + 31593631 = 31594484
877 + 31593607 = 31594484
967 + 31593517 = 31594484

Showing the first eight; more decompositions exist.
