Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456088, here are decompositions:

67 + 31456021 = 31456088
127 + 31455961 = 31456088
199 + 31455889 = 31456088
211 + 31455877 = 31456088
229 + 31455859 = 31456088
337 + 31455751 = 31456088
439 + 31455649 = 31456088
457 + 31455631 = 31456088

Showing the first eight; more decompositions exist.
