Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751492, here are decompositions:

23 + 8751469 = 8751492
31 + 8751461 = 8751492
41 + 8751451 = 8751492
53 + 8751439 = 8751492
151 + 8751341 = 8751492
163 + 8751329 = 8751492
173 + 8751319 = 8751492
241 + 8751251 = 8751492

Showing the first eight; more decompositions exist.
