Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496804, here are decompositions:

13 + 31496791 = 31496804
127 + 31496677 = 31496804
193 + 31496611 = 31496804
211 + 31496593 = 31496804
433 + 31496371 = 31496804
487 + 31496317 = 31496804
541 + 31496263 = 31496804
631 + 31496173 = 31496804

Showing the first eight; more decompositions exist.
