Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457654, here are decompositions:

13 + 31457641 = 31457654
43 + 31457611 = 31457654
97 + 31457557 = 31457654
271 + 31457383 = 31457654
307 + 31457347 = 31457654
313 + 31457341 = 31457654
367 + 31457287 = 31457654
727 + 31456927 = 31457654

Showing the first eight; more decompositions exist.
