Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469394, here are decompositions:

7 + 31469387 = 31469394
37 + 31469357 = 31469394
41 + 31469353 = 31469394
67 + 31469327 = 31469394
71 + 31469323 = 31469394
101 + 31469293 = 31469394
107 + 31469287 = 31469394
197 + 31469197 = 31469394

Showing the first eight; more decompositions exist.
