Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733440, here are decompositions:

7 + 8733433 = 8733440
43 + 8733397 = 8733440
127 + 8733313 = 8733440
139 + 8733301 = 8733440
181 + 8733259 = 8733440
193 + 8733247 = 8733440
277 + 8733163 = 8733440
283 + 8733157 = 8733440

Showing the first eight; more decompositions exist.
