Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740436, here are decompositions:

7 + 8740429 = 8740436
43 + 8740393 = 8740436
109 + 8740327 = 8740436
163 + 8740273 = 8740436
307 + 8740129 = 8740436
349 + 8740087 = 8740436
433 + 8740003 = 8740436
499 + 8739937 = 8740436

Showing the first eight; more decompositions exist.
