Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470364, here are decompositions:

5 + 31470359 = 31470364
11 + 31470353 = 31470364
41 + 31470323 = 31470364
71 + 31470293 = 31470364
197 + 31470167 = 31470364
461 + 31469903 = 31470364
503 + 31469861 = 31470364
641 + 31469723 = 31470364

Showing the first eight; more decompositions exist.
