Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470974, here are decompositions:

61 + 31470913 = 31470974
127 + 31470847 = 31470974
151 + 31470823 = 31470974
181 + 31470793 = 31470974
193 + 31470781 = 31470974
313 + 31470661 = 31470974
751 + 31470223 = 31470974
757 + 31470217 = 31470974

Showing the first eight; more decompositions exist.
