Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496898, here are decompositions:

71 + 31496827 = 31496898
79 + 31496819 = 31496898
89 + 31496809 = 31496898
107 + 31496791 = 31496898
157 + 31496741 = 31496898
179 + 31496719 = 31496898
227 + 31496671 = 31496898
229 + 31496669 = 31496898

Showing the first eight; more decompositions exist.
