Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470770, here are decompositions:

61 + 31470709 = 31470770
109 + 31470661 = 31470770
151 + 31470619 = 31470770
223 + 31470547 = 31470770
433 + 31470337 = 31470770
547 + 31470223 = 31470770
571 + 31470199 = 31470770
577 + 31470193 = 31470770

Showing the first eight; more decompositions exist.
