Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594492, here are decompositions:

3 + 31594489 = 31594492
29 + 31594463 = 31594492
71 + 31594421 = 31594492
359 + 31594133 = 31594492
431 + 31594061 = 31594492
443 + 31594049 = 31594492
509 + 31593983 = 31594492
653 + 31593839 = 31594492

Showing the first eight; more decompositions exist.
