Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452962, here are decompositions:

19 + 31452943 = 31452962
61 + 31452901 = 31452962
103 + 31452859 = 31452962
193 + 31452769 = 31452962
199 + 31452763 = 31452962
223 + 31452739 = 31452962
241 + 31452721 = 31452962
313 + 31452649 = 31452962

Showing the first eight; more decompositions exist.
