Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496904, here are decompositions:

31 + 31496873 = 31496904
41 + 31496863 = 31496904
113 + 31496791 = 31496904
163 + 31496741 = 31496904
211 + 31496693 = 31496904
227 + 31496677 = 31496904
233 + 31496671 = 31496904
293 + 31496611 = 31496904

Showing the first eight; more decompositions exist.
