Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546472, here are decompositions:

3 + 31546469 = 31546472
79 + 31546393 = 31546472
103 + 31546369 = 31546472
193 + 31546279 = 31546472
241 + 31546231 = 31546472
313 + 31546159 = 31546472
409 + 31546063 = 31546472
571 + 31545901 = 31546472

Showing the first eight; more decompositions exist.
