Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592566, here are decompositions:

113 + 31592453 = 31592566
149 + 31592417 = 31592566
197 + 31592369 = 31592566
347 + 31592219 = 31592566
353 + 31592213 = 31592566
443 + 31592123 = 31592566
569 + 31591997 = 31592566
587 + 31591979 = 31592566

Showing the first eight; more decompositions exist.
