Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729392, here are decompositions:

3 + 8729389 = 8729392
59 + 8729333 = 8729392
83 + 8729309 = 8729392
101 + 8729291 = 8729392
149 + 8729243 = 8729392
173 + 8729219 = 8729392
251 + 8729141 = 8729392
293 + 8729099 = 8729392

Showing the first eight; more decompositions exist.
