Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457324, here are decompositions:

13 + 31457311 = 31457324
37 + 31457287 = 31457324
97 + 31457227 = 31457324
397 + 31456927 = 31457324
421 + 31456903 = 31457324
433 + 31456891 = 31457324
673 + 31456651 = 31457324
727 + 31456597 = 31457324

Showing the first eight; more decompositions exist.
