Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594154, here are decompositions:

3 + 31594151 = 31594154
73 + 31594081 = 31594154
211 + 31593943 = 31594154
223 + 31593931 = 31594154
367 + 31593787 = 31594154
433 + 31593721 = 31594154
523 + 31593631 = 31594154
541 + 31593613 = 31594154

Showing the first eight; more decompositions exist.
