Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463372, here are decompositions:

19 + 31463353 = 31463372
43 + 31463329 = 31463372
103 + 31463269 = 31463372
211 + 31463161 = 31463372
349 + 31463023 = 31463372
439 + 31462933 = 31463372
463 + 31462909 = 31463372
541 + 31462831 = 31463372

Showing the first eight; more decompositions exist.
