Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484864, here are decompositions:

43 + 31484821 = 31484864
67 + 31484797 = 31484864
331 + 31484533 = 31484864
487 + 31484377 = 31484864
547 + 31484317 = 31484864
661 + 31484203 = 31484864
883 + 31483981 = 31484864
907 + 31483957 = 31484864

Showing the first eight; more decompositions exist.
