Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627990, here are decompositions:

3 + 8627987 = 8627990
13 + 8627977 = 8627990
37 + 8627953 = 8627990
43 + 8627947 = 8627990
79 + 8627911 = 8627990
97 + 8627893 = 8627990
139 + 8627851 = 8627990
157 + 8627833 = 8627990

Showing the first eight; more decompositions exist.
