Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468852, here are decompositions:

3 + 31468849 = 31468852
29 + 31468823 = 31468852
59 + 31468793 = 31468852
263 + 31468589 = 31468852
281 + 31468571 = 31468852
293 + 31468559 = 31468852
353 + 31468499 = 31468852
449 + 31468403 = 31468852

Showing the first eight; more decompositions exist.
