Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594516, here are decompositions:

53 + 31594463 = 31594516
269 + 31594247 = 31594516
353 + 31594163 = 31594516
383 + 31594133 = 31594516
419 + 31594097 = 31594516
467 + 31594049 = 31594516
557 + 31593959 = 31594516
563 + 31593953 = 31594516

Showing the first eight; more decompositions exist.
