Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496326, here are decompositions:

5 + 31496321 = 31496326
107 + 31496219 = 31496326
227 + 31496099 = 31496326
269 + 31496057 = 31496326
347 + 31495979 = 31496326
467 + 31495859 = 31496326
479 + 31495847 = 31496326
569 + 31495757 = 31496326

Showing the first eight; more decompositions exist.
