Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613740, here are decompositions:

7 + 8613733 = 8613740
181 + 8613559 = 8613740
193 + 8613547 = 8613740
211 + 8613529 = 8613740
277 + 8613463 = 8613740
283 + 8613457 = 8613740
313 + 8613427 = 8613740
349 + 8613391 = 8613740

Showing the first eight; more decompositions exist.
