Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452596, here are decompositions:

13 + 31452583 = 31452596
67 + 31452529 = 31452596
79 + 31452517 = 31452596
103 + 31452493 = 31452596
229 + 31452367 = 31452596
313 + 31452283 = 31452596
397 + 31452199 = 31452596
499 + 31452097 = 31452596

Showing the first eight; more decompositions exist.
