Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463042, here are decompositions:

19 + 31463023 = 31463042
73 + 31462969 = 31463042
109 + 31462933 = 31463042
211 + 31462831 = 31463042
271 + 31462771 = 31463042
283 + 31462759 = 31463042
313 + 31462729 = 31463042
433 + 31462609 = 31463042

Showing the first eight; more decompositions exist.
