Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454864, here are decompositions:

37 + 31454827 = 31454864
127 + 31454737 = 31454864
163 + 31454701 = 31454864
211 + 31454653 = 31454864
277 + 31454587 = 31454864
367 + 31454497 = 31454864
433 + 31454431 = 31454864
487 + 31454377 = 31454864

Showing the first eight; more decompositions exist.
