Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546580, here are decompositions:

7 + 31546573 = 31546580
97 + 31546483 = 31546580
193 + 31546387 = 31546580
211 + 31546369 = 31546580
229 + 31546351 = 31546580
277 + 31546303 = 31546580
313 + 31546267 = 31546580
349 + 31546231 = 31546580

Showing the first eight; more decompositions exist.
