Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649202, here are decompositions:

5 + 8649197 = 8649202
11 + 8649191 = 8649202
131 + 8649071 = 8649202
173 + 8649029 = 8649202
179 + 8649023 = 8649202
281 + 8648921 = 8649202
389 + 8648813 = 8649202
461 + 8648741 = 8649202

Showing the first eight; more decompositions exist.
