Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452056, here are decompositions:

37 + 31452019 = 31452056
43 + 31452013 = 31452056
127 + 31451929 = 31452056
199 + 31451857 = 31452056
439 + 31451617 = 31452056
619 + 31451437 = 31452056
673 + 31451383 = 31452056
709 + 31451347 = 31452056

Showing the first eight; more decompositions exist.
