Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672398, here are decompositions:

11 + 8672387 = 8672398
17 + 8672381 = 8672398
101 + 8672297 = 8672398
131 + 8672267 = 8672398
191 + 8672207 = 8672398
197 + 8672201 = 8672398
281 + 8672117 = 8672398
311 + 8672087 = 8672398

Showing the first eight; more decompositions exist.
