Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726830, here are decompositions:

29 + 8726801 = 8726830
41 + 8726789 = 8726830
53 + 8726777 = 8726830
71 + 8726759 = 8726830
107 + 8726723 = 8726830
131 + 8726699 = 8726830
197 + 8726633 = 8726830
257 + 8726573 = 8726830

Showing the first eight; more decompositions exist.
