Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745248, here are decompositions:

7 + 8745241 = 8745248
79 + 8745169 = 8745248
151 + 8745097 = 8745248
181 + 8745067 = 8745248
229 + 8745019 = 8745248
307 + 8744941 = 8745248
331 + 8744917 = 8745248
541 + 8744707 = 8745248

Showing the first eight; more decompositions exist.
