Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620700, here are decompositions:

13 + 8620687 = 8620700
37 + 8620663 = 8620700
61 + 8620639 = 8620700
79 + 8620621 = 8620700
97 + 8620603 = 8620700
157 + 8620543 = 8620700
271 + 8620429 = 8620700
307 + 8620393 = 8620700

Showing the first eight; more decompositions exist.
