Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594690, here are decompositions:

107 + 31594583 = 31594690
137 + 31594553 = 31594690
227 + 31594463 = 31594690
269 + 31594421 = 31594690
317 + 31594373 = 31594690
359 + 31594331 = 31594690
419 + 31594271 = 31594690
443 + 31594247 = 31594690

Showing the first eight; more decompositions exist.
