Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724444, here are decompositions:

7 + 8724437 = 8724444
23 + 8724421 = 8724444
67 + 8724377 = 8724444
73 + 8724371 = 8724444
97 + 8724347 = 8724444
151 + 8724293 = 8724444
181 + 8724263 = 8724444
191 + 8724253 = 8724444

Showing the first eight; more decompositions exist.
