Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468686, here are decompositions:

19 + 31468667 = 31468686
89 + 31468597 = 31468686
97 + 31468589 = 31468686
113 + 31468573 = 31468686
127 + 31468559 = 31468686
157 + 31468529 = 31468686
163 + 31468523 = 31468686
233 + 31468453 = 31468686

Showing the first eight; more decompositions exist.
