Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469376, here are decompositions:

19 + 31469357 = 31469376
23 + 31469353 = 31469376
53 + 31469323 = 31469376
73 + 31469303 = 31469376
83 + 31469293 = 31469376
89 + 31469287 = 31469376
97 + 31469279 = 31469376
137 + 31469239 = 31469376

Showing the first eight; more decompositions exist.
