Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484692, here are decompositions:

149 + 31484543 = 31484692
179 + 31484513 = 31484692
353 + 31484339 = 31484692
389 + 31484303 = 31484692
563 + 31484129 = 31484692
599 + 31484093 = 31484692
773 + 31483919 = 31484692
809 + 31483883 = 31484692

Showing the first eight; more decompositions exist.
