Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745444, here are decompositions:

7 + 8745437 = 8745444
101 + 8745343 = 8745444
137 + 8745307 = 8745444
241 + 8745203 = 8745444
283 + 8745161 = 8745444
311 + 8745133 = 8745444
347 + 8745097 = 8745444
373 + 8745071 = 8745444

Showing the first eight; more decompositions exist.
