Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452716, here are decompositions:

67 + 31452649 = 31452716
109 + 31452607 = 31452716
199 + 31452517 = 31452716
223 + 31452493 = 31452716
349 + 31452367 = 31452716
433 + 31452283 = 31452716
619 + 31452097 = 31452716
709 + 31452007 = 31452716

Showing the first eight; more decompositions exist.
