Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453316, here are decompositions:

67 + 31453249 = 31453316
109 + 31453207 = 31453316
157 + 31453159 = 31453316
277 + 31453039 = 31453316
373 + 31452943 = 31453316
457 + 31452859 = 31453316
487 + 31452829 = 31453316
523 + 31452793 = 31453316

Showing the first eight; more decompositions exist.
