Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468896, here are decompositions:

47 + 31468849 = 31468896
73 + 31468823 = 31468896
103 + 31468793 = 31468896
139 + 31468757 = 31468896
197 + 31468699 = 31468896
229 + 31468667 = 31468896
307 + 31468589 = 31468896
337 + 31468559 = 31468896

Showing the first eight; more decompositions exist.
