Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592884, here are decompositions:

41 + 31592843 = 31592884
137 + 31592747 = 31592884
233 + 31592651 = 31592884
263 + 31592621 = 31592884
317 + 31592567 = 31592884
353 + 31592531 = 31592884
431 + 31592453 = 31592884
461 + 31592423 = 31592884

Showing the first eight; more decompositions exist.
