Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452266, here are decompositions:

67 + 31452199 = 31452266
337 + 31451929 = 31452266
397 + 31451869 = 31452266
409 + 31451857 = 31452266
739 + 31451527 = 31452266
829 + 31451437 = 31452266
883 + 31451383 = 31452266
919 + 31451347 = 31452266

Showing the first eight; more decompositions exist.
