Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453094, here are decompositions:

73 + 31453021 = 31453094
151 + 31452943 = 31453094
193 + 31452901 = 31453094
331 + 31452763 = 31453094
367 + 31452727 = 31453094
373 + 31452721 = 31453094
487 + 31452607 = 31453094
523 + 31452571 = 31453094

Showing the first eight; more decompositions exist.
