Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594726, here are decompositions:

113 + 31594613 = 31594726
173 + 31594553 = 31594726
179 + 31594547 = 31594726
263 + 31594463 = 31594726
353 + 31594373 = 31594726
479 + 31594247 = 31594726
563 + 31594163 = 31594726
593 + 31594133 = 31594726

Showing the first eight; more decompositions exist.
