Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592806, here are decompositions:

59 + 31592747 = 31592806
239 + 31592567 = 31592806
317 + 31592489 = 31592806
353 + 31592453 = 31592806
359 + 31592447 = 31592806
383 + 31592423 = 31592806
389 + 31592417 = 31592806
449 + 31592357 = 31592806

Showing the first eight; more decompositions exist.
