Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469418, here are decompositions:

7 + 31469411 = 31469418
11 + 31469407 = 31469418
31 + 31469387 = 31469418
61 + 31469357 = 31469418
131 + 31469287 = 31469418
139 + 31469279 = 31469418
179 + 31469239 = 31469418
241 + 31469177 = 31469418

Showing the first eight; more decompositions exist.
