Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470370, here are decompositions:

11 + 31470359 = 31470370
17 + 31470353 = 31470370
47 + 31470323 = 31470370
149 + 31470221 = 31470370
227 + 31470143 = 31470370
383 + 31469987 = 31470370
467 + 31469903 = 31470370
509 + 31469861 = 31470370

Showing the first eight; more decompositions exist.
