Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749452, here are decompositions:

13 + 8749439 = 8749452
29 + 8749423 = 8749452
31 + 8749421 = 8749452
109 + 8749343 = 8749452
223 + 8749229 = 8749452
233 + 8749219 = 8749452
311 + 8749141 = 8749452
331 + 8749121 = 8749452

Showing the first eight; more decompositions exist.
