Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746428, here are decompositions:

29 + 8746399 = 8746428
37 + 8746391 = 8746428
59 + 8746369 = 8746428
71 + 8746357 = 8746428
127 + 8746301 = 8746428
157 + 8746271 = 8746428
167 + 8746261 = 8746428
191 + 8746237 = 8746428

Showing the first eight; more decompositions exist.
