Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592938, here are decompositions:

17 + 31592921 = 31592938
89 + 31592849 = 31592938
191 + 31592747 = 31592938
317 + 31592621 = 31592938
449 + 31592489 = 31592938
491 + 31592447 = 31592938
521 + 31592417 = 31592938
569 + 31592369 = 31592938

Showing the first eight; more decompositions exist.
