Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468712, here are decompositions:

13 + 31468699 = 31468712
139 + 31468573 = 31468712
241 + 31468471 = 31468712
313 + 31468399 = 31468712
859 + 31467853 = 31468712
883 + 31467829 = 31468712
991 + 31467721 = 31468712
1021 + 31467691 = 31468712

Showing the first eight; more decompositions exist.
