Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471852, here are decompositions:

3 + 31471849 = 31471852
29 + 31471823 = 31471852
53 + 31471799 = 31471852
89 + 31471763 = 31471852
149 + 31471703 = 31471852
383 + 31471469 = 31471852
479 + 31471373 = 31471852
491 + 31471361 = 31471852

Showing the first eight; more decompositions exist.
