Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637740, here are decompositions:

43 + 8637697 = 8637740
73 + 8637667 = 8637740
103 + 8637637 = 8637740
313 + 8637427 = 8637740
367 + 8637373 = 8637740
421 + 8637319 = 8637740
439 + 8637301 = 8637740
487 + 8637253 = 8637740

Showing the first eight; more decompositions exist.
