Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470554, here are decompositions:

7 + 31470547 = 31470554
331 + 31470223 = 31470554
337 + 31470217 = 31470554
457 + 31470097 = 31470554
487 + 31470067 = 31470554
541 + 31470013 = 31470554
601 + 31469953 = 31470554
631 + 31469923 = 31470554

Showing the first eight; more decompositions exist.
