Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469430, here are decompositions:

7 + 31469423 = 31469430
19 + 31469411 = 31469430
23 + 31469407 = 31469430
43 + 31469387 = 31469430
73 + 31469357 = 31469430
103 + 31469327 = 31469430
107 + 31469323 = 31469430
127 + 31469303 = 31469430

Showing the first eight; more decompositions exist.
