Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496948, here are decompositions:

31 + 31496917 = 31496948
139 + 31496809 = 31496948
157 + 31496791 = 31496948
229 + 31496719 = 31496948
271 + 31496677 = 31496948
277 + 31496671 = 31496948
337 + 31496611 = 31496948
349 + 31496599 = 31496948

Showing the first eight; more decompositions exist.
