Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453496, here are decompositions:

13 + 31453483 = 31453496
103 + 31453393 = 31453496
163 + 31453333 = 31453496
229 + 31453267 = 31453496
337 + 31453159 = 31453496
457 + 31453039 = 31453496
523 + 31452973 = 31453496
727 + 31452769 = 31453496

Showing the first eight; more decompositions exist.
