Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470962, here are decompositions:

73 + 31470889 = 31470962
109 + 31470853 = 31470962
139 + 31470823 = 31470962
163 + 31470799 = 31470962
181 + 31470781 = 31470962
241 + 31470721 = 31470962
739 + 31470223 = 31470962
769 + 31470193 = 31470962

Showing the first eight; more decompositions exist.
