Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452896, here are decompositions:

37 + 31452859 = 31452896
67 + 31452829 = 31452896
103 + 31452793 = 31452896
127 + 31452769 = 31452896
157 + 31452739 = 31452896
229 + 31452667 = 31452896
313 + 31452583 = 31452896
367 + 31452529 = 31452896

Showing the first eight; more decompositions exist.
