Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457714, here are decompositions:

7 + 31457707 = 31457714
73 + 31457641 = 31457714
103 + 31457611 = 31457714
157 + 31457557 = 31457714
331 + 31457383 = 31457714
367 + 31457347 = 31457714
373 + 31457341 = 31457714
487 + 31457227 = 31457714

Showing the first eight; more decompositions exist.
