Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457696, here are decompositions:

139 + 31457557 = 31457696
313 + 31457383 = 31457696
349 + 31457347 = 31457696
367 + 31457329 = 31457696
409 + 31457287 = 31457696
547 + 31457149 = 31457696
577 + 31457119 = 31457696
769 + 31456927 = 31457696

Showing the first eight; more decompositions exist.
