Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453952, here are decompositions:

43 + 31453909 = 31453952
73 + 31453879 = 31453952
139 + 31453813 = 31453952
241 + 31453711 = 31453952
619 + 31453333 = 31453952
631 + 31453321 = 31453952
811 + 31453141 = 31453952
1009 + 31452943 = 31453952

Showing the first eight; more decompositions exist.
