Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470932, here are decompositions:

19 + 31470913 = 31470932
43 + 31470889 = 31470932
79 + 31470853 = 31470932
109 + 31470823 = 31470932
139 + 31470793 = 31470932
151 + 31470781 = 31470932
211 + 31470721 = 31470932
223 + 31470709 = 31470932

Showing the first eight; more decompositions exist.
