Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594054, here are decompositions:

5 + 31594049 = 31594054
71 + 31593983 = 31594054
101 + 31593953 = 31594054
257 + 31593797 = 31594054
491 + 31593563 = 31594054
521 + 31593533 = 31594054
563 + 31593491 = 31594054
593 + 31593461 = 31594054

Showing the first eight; more decompositions exist.
