Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594570, here are decompositions:

17 + 31594553 = 31594570
23 + 31594547 = 31594570
107 + 31594463 = 31594570
149 + 31594421 = 31594570
197 + 31594373 = 31594570
239 + 31594331 = 31594570
419 + 31594151 = 31594570
509 + 31594061 = 31594570

Showing the first eight; more decompositions exist.
