Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619802, here are decompositions:

5 + 8619797 = 8619802
11 + 8619791 = 8619802
29 + 8619773 = 8619802
83 + 8619719 = 8619802
89 + 8619713 = 8619802
179 + 8619623 = 8619802
251 + 8619551 = 8619802
263 + 8619539 = 8619802

Showing the first eight; more decompositions exist.
