Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463398, here are decompositions:

11 + 31463387 = 31463398
137 + 31463261 = 31463398
149 + 31463249 = 31463398
251 + 31463147 = 31463398
311 + 31463087 = 31463398
419 + 31462979 = 31463398
467 + 31462931 = 31463398
509 + 31462889 = 31463398

Showing the first eight; more decompositions exist.
