Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469402, here are decompositions:

79 + 31469323 = 31469402
103 + 31469299 = 31469402
109 + 31469293 = 31469402
163 + 31469239 = 31469402
193 + 31469209 = 31469402
271 + 31469131 = 31469402
409 + 31468993 = 31469402
439 + 31468963 = 31469402

Showing the first eight; more decompositions exist.
