Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594480, here are decompositions:

17 + 31594463 = 31594480
59 + 31594421 = 31594480
107 + 31594373 = 31594480
149 + 31594331 = 31594480
233 + 31594247 = 31594480
317 + 31594163 = 31594480
347 + 31594133 = 31594480
383 + 31594097 = 31594480

Showing the first eight; more decompositions exist.
