Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735440, here are decompositions:

11 + 8735429 = 8735440
23 + 8735417 = 8735440
101 + 8735339 = 8735440
149 + 8735291 = 8735440
191 + 8735249 = 8735440
257 + 8735183 = 8735440
401 + 8735039 = 8735440
521 + 8734919 = 8735440

Showing the first eight; more decompositions exist.
