Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470658, here are decompositions:

5 + 31470653 = 31470658
17 + 31470641 = 31470658
29 + 31470629 = 31470658
101 + 31470557 = 31470658
449 + 31470209 = 31470658
491 + 31470167 = 31470658
797 + 31469861 = 31470658
809 + 31469849 = 31470658

Showing the first eight; more decompositions exist.
