Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453262, here are decompositions:

13 + 31453249 = 31453262
103 + 31453159 = 31453262
223 + 31453039 = 31453262
241 + 31453021 = 31453262
433 + 31452829 = 31453262
499 + 31452763 = 31453262
523 + 31452739 = 31453262
541 + 31452721 = 31453262

Showing the first eight; more decompositions exist.
