Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453106, here are decompositions:

67 + 31453039 = 31453106
163 + 31452943 = 31453106
277 + 31452829 = 31453106
313 + 31452793 = 31453106
337 + 31452769 = 31453106
367 + 31452739 = 31453106
379 + 31452727 = 31453106
439 + 31452667 = 31453106

Showing the first eight; more decompositions exist.
