Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733640, here are decompositions:

23 + 8733617 = 8733640
89 + 8733551 = 8733640
173 + 8733467 = 8733640
239 + 8733401 = 8733640
317 + 8733323 = 8733640
359 + 8733281 = 8733640
389 + 8733251 = 8733640
467 + 8733173 = 8733640

Showing the first eight; more decompositions exist.
