Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463012, here are decompositions:

43 + 31462969 = 31463012
79 + 31462933 = 31463012
103 + 31462909 = 31463012
181 + 31462831 = 31463012
241 + 31462771 = 31463012
283 + 31462729 = 31463012
409 + 31462603 = 31463012
421 + 31462591 = 31463012

Showing the first eight; more decompositions exist.
