Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454042, here are decompositions:

19 + 31454023 = 31454042
73 + 31453969 = 31454042
163 + 31453879 = 31454042
229 + 31453813 = 31454042
331 + 31453711 = 31454042
541 + 31453501 = 31454042
709 + 31453333 = 31454042
883 + 31453159 = 31454042

Showing the first eight; more decompositions exist.
