Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634740, here are decompositions:

43 + 8634697 = 8634740
61 + 8634679 = 8634740
73 + 8634667 = 8634740
223 + 8634517 = 8634740
271 + 8634469 = 8634740
313 + 8634427 = 8634740
349 + 8634391 = 8634740
487 + 8634253 = 8634740

Showing the first eight; more decompositions exist.
