Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633740, here are decompositions:

29 + 8633711 = 8633740
41 + 8633699 = 8633740
107 + 8633633 = 8633740
173 + 8633567 = 8633740
251 + 8633489 = 8633740
281 + 8633459 = 8633740
317 + 8633423 = 8633740
359 + 8633381 = 8633740

Showing the first eight; more decompositions exist.
