Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457594, here are decompositions:

37 + 31457557 = 31457594
211 + 31457383 = 31457594
283 + 31457311 = 31457594
307 + 31457287 = 31457594
367 + 31457227 = 31457594
523 + 31457071 = 31457594
691 + 31456903 = 31457594
853 + 31456741 = 31457594

Showing the first eight; more decompositions exist.
