Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469352, here are decompositions:

29 + 31469323 = 31469352
53 + 31469299 = 31469352
59 + 31469293 = 31469352
73 + 31469279 = 31469352
113 + 31469239 = 31469352
251 + 31469101 = 31469352
283 + 31469069 = 31469352
311 + 31469041 = 31469352

Showing the first eight; more decompositions exist.
