Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470598, here are decompositions:

17 + 31470581 = 31470598
41 + 31470557 = 31470598
239 + 31470359 = 31470598
389 + 31470209 = 31470598
431 + 31470167 = 31470598
857 + 31469741 = 31470598
977 + 31469621 = 31470598
1019 + 31469579 = 31470598

Showing the first eight; more decompositions exist.
