Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457954, here are decompositions:

43 + 31457911 = 31457954
97 + 31457857 = 31457954
211 + 31457743 = 31457954
313 + 31457641 = 31457954
397 + 31457557 = 31457954
571 + 31457383 = 31457954
607 + 31457347 = 31457954
613 + 31457341 = 31457954

Showing the first eight; more decompositions exist.
