Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594672, here are decompositions:

59 + 31594613 = 31594672
89 + 31594583 = 31594672
251 + 31594421 = 31594672
401 + 31594271 = 31594672
479 + 31594193 = 31594672
509 + 31594163 = 31594672
521 + 31594151 = 31594672
719 + 31593953 = 31594672

Showing the first eight; more decompositions exist.
