Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472910, here are decompositions:

19 + 31472891 = 31472910
23 + 31472887 = 31472910
31 + 31472879 = 31472910
43 + 31472867 = 31472910
59 + 31472851 = 31472910
61 + 31472849 = 31472910
71 + 31472839 = 31472910
83 + 31472827 = 31472910

Showing the first eight; more decompositions exist.
