Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471044, here are decompositions:

13 + 31471031 = 31471044
37 + 31471007 = 31471044
43 + 31471001 = 31471044
47 + 31470997 = 31471044
53 + 31470991 = 31471044
67 + 31470977 = 31471044
103 + 31470941 = 31471044
127 + 31470917 = 31471044

Showing the first eight; more decompositions exist.
