Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594454, here are decompositions:

61 + 31594393 = 31594454
103 + 31594351 = 31594454
181 + 31594273 = 31594454
373 + 31594081 = 31594454
523 + 31593931 = 31594454
691 + 31593763 = 31594454
733 + 31593721 = 31594454
751 + 31593703 = 31594454

Showing the first eight; more decompositions exist.
