Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733390, here are decompositions:

67 + 8733323 = 8733390
73 + 8733317 = 8733390
79 + 8733311 = 8733390
89 + 8733301 = 8733390
109 + 8733281 = 8733390
131 + 8733259 = 8733390
139 + 8733251 = 8733390
227 + 8733163 = 8733390

Showing the first eight; more decompositions exist.
