Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747248, here are decompositions:

5 + 8747243 = 8747248
89 + 8747159 = 8747248
137 + 8747111 = 8747248
269 + 8746979 = 8747248
281 + 8746967 = 8747248
311 + 8746937 = 8747248
401 + 8746847 = 8747248
449 + 8746799 = 8747248

Showing the first eight; more decompositions exist.
