Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592770, here are decompositions:

23 + 31592747 = 31592770
107 + 31592663 = 31592770
149 + 31592621 = 31592770
239 + 31592531 = 31592770
281 + 31592489 = 31592770
317 + 31592453 = 31592770
347 + 31592423 = 31592770
353 + 31592417 = 31592770

Showing the first eight; more decompositions exist.
