Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452566, here are decompositions:

37 + 31452529 = 31452566
73 + 31452493 = 31452566
199 + 31452367 = 31452566
283 + 31452283 = 31452566
367 + 31452199 = 31452566
487 + 31452079 = 31452566
547 + 31452019 = 31452566
709 + 31451857 = 31452566

Showing the first eight; more decompositions exist.
