Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620460, here are decompositions:

31 + 8620429 = 8620460
67 + 8620393 = 8620460
193 + 8620267 = 8620460
229 + 8620231 = 8620460
241 + 8620219 = 8620460
271 + 8620189 = 8620460
349 + 8620111 = 8620460
397 + 8620063 = 8620460

Showing the first eight; more decompositions exist.
