Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469468, here are decompositions:

61 + 31469407 = 31469468
181 + 31469287 = 31469468
229 + 31469239 = 31469468
271 + 31469197 = 31469468
337 + 31469131 = 31469468
367 + 31469101 = 31469468
607 + 31468861 = 31469468
619 + 31468849 = 31469468

Showing the first eight; more decompositions exist.
