Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496798, here are decompositions:

7 + 31496791 = 31496798
19 + 31496779 = 31496798
79 + 31496719 = 31496798
127 + 31496671 = 31496798
199 + 31496599 = 31496798
211 + 31496587 = 31496798
349 + 31496449 = 31496798
379 + 31496419 = 31496798

Showing the first eight; more decompositions exist.
