Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455896, here are decompositions:

7 + 31455889 = 31455896
19 + 31455877 = 31455896
37 + 31455859 = 31455896
67 + 31455829 = 31455896
193 + 31455703 = 31455896
397 + 31455499 = 31455896
463 + 31455433 = 31455896
487 + 31455409 = 31455896

Showing the first eight; more decompositions exist.
