Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559896, here are decompositions:

47 + 31559849 = 31559896
83 + 31559813 = 31559896
113 + 31559783 = 31559896
197 + 31559699 = 31559896
257 + 31559639 = 31559896
359 + 31559537 = 31559896
449 + 31559447 = 31559896
479 + 31559417 = 31559896

Showing the first eight; more decompositions exist.
