Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729248, here are decompositions:

5 + 8729243 = 8729248
29 + 8729219 = 8729248
41 + 8729207 = 8729248
107 + 8729141 = 8729248
131 + 8729117 = 8729248
149 + 8729099 = 8729248
167 + 8729081 = 8729248
191 + 8729057 = 8729248

Showing the first eight; more decompositions exist.
