Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470352, here are decompositions:

29 + 31470323 = 31470352
59 + 31470293 = 31470352
131 + 31470221 = 31470352
449 + 31469903 = 31470352
491 + 31469861 = 31470352
503 + 31469849 = 31470352
569 + 31469783 = 31470352
773 + 31469579 = 31470352

Showing the first eight; more decompositions exist.
