Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729578, here are decompositions:

149 + 8729429 = 8729578
167 + 8729411 = 8729578
251 + 8729327 = 8729578
269 + 8729309 = 8729578
359 + 8729219 = 8729578
461 + 8729117 = 8729578
479 + 8729099 = 8729578
521 + 8729057 = 8729578

Showing the first eight; more decompositions exist.
