Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470058, here are decompositions:

71 + 31469987 = 31470058
197 + 31469861 = 31470058
317 + 31469741 = 31470058
479 + 31469579 = 31470058
617 + 31469441 = 31470058
647 + 31469411 = 31470058
701 + 31469357 = 31470058
881 + 31469177 = 31470058

Showing the first eight; more decompositions exist.
