Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470954, here are decompositions:

13 + 31470941 = 31470954
37 + 31470917 = 31470954
41 + 31470913 = 31470954
43 + 31470911 = 31470954
101 + 31470853 = 31470954
107 + 31470847 = 31470954
127 + 31470827 = 31470954
131 + 31470823 = 31470954

Showing the first eight; more decompositions exist.
