Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559926, here are decompositions:

113 + 31559813 = 31559926
149 + 31559777 = 31559926
227 + 31559699 = 31559926
239 + 31559687 = 31559926
353 + 31559573 = 31559926
389 + 31559537 = 31559926
479 + 31559447 = 31559926
509 + 31559417 = 31559926

Showing the first eight; more decompositions exist.
