Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594450, here are decompositions:

29 + 31594421 = 31594450
179 + 31594271 = 31594450
257 + 31594193 = 31594450
317 + 31594133 = 31594450
353 + 31594097 = 31594450
389 + 31594061 = 31594450
401 + 31594049 = 31594450
467 + 31593983 = 31594450

Showing the first eight; more decompositions exist.
