Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452224, here are decompositions:

43 + 31452181 = 31452224
103 + 31452121 = 31452224
127 + 31452097 = 31452224
163 + 31452061 = 31452224
211 + 31452013 = 31452224
367 + 31451857 = 31452224
607 + 31451617 = 31452224
733 + 31451491 = 31452224

Showing the first eight; more decompositions exist.
