Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496888, here are decompositions:

61 + 31496827 = 31496888
79 + 31496809 = 31496888
97 + 31496791 = 31496888
109 + 31496779 = 31496888
211 + 31496677 = 31496888
277 + 31496611 = 31496888
337 + 31496551 = 31496888
349 + 31496539 = 31496888

Showing the first eight; more decompositions exist.
