Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457852, here are decompositions:

3 + 31457849 = 31457852
31 + 31457821 = 31457852
109 + 31457743 = 31457852
211 + 31457641 = 31457852
241 + 31457611 = 31457852
373 + 31457479 = 31457852
523 + 31457329 = 31457852
541 + 31457311 = 31457852

Showing the first eight; more decompositions exist.
