Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469370, here are decompositions:

13 + 31469357 = 31469370
17 + 31469353 = 31469370
43 + 31469327 = 31469370
47 + 31469323 = 31469370
67 + 31469303 = 31469370
71 + 31469299 = 31469370
83 + 31469287 = 31469370
131 + 31469239 = 31469370

Showing the first eight; more decompositions exist.
