Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457624, here are decompositions:

13 + 31457611 = 31457624
67 + 31457557 = 31457624
241 + 31457383 = 31457624
277 + 31457347 = 31457624
283 + 31457341 = 31457624
313 + 31457311 = 31457624
337 + 31457287 = 31457624
397 + 31457227 = 31457624

Showing the first eight; more decompositions exist.
