Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453348, here are decompositions:

107 + 31453241 = 31453348
167 + 31453181 = 31453348
191 + 31453157 = 31453348
599 + 31452749 = 31453348
617 + 31452731 = 31453348
761 + 31452587 = 31453348
809 + 31452539 = 31453348
821 + 31452527 = 31453348

Showing the first eight; more decompositions exist.
