Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463930, here are decompositions:

19 + 31463911 = 31463930
37 + 31463893 = 31463930
73 + 31463857 = 31463930
103 + 31463827 = 31463930
151 + 31463779 = 31463930
163 + 31463767 = 31463930
241 + 31463689 = 31463930
397 + 31463533 = 31463930

Showing the first eight; more decompositions exist.
