Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720846, here are decompositions:

7 + 8720839 = 8720846
37 + 8720809 = 8720846
73 + 8720773 = 8720846
139 + 8720707 = 8720846
157 + 8720689 = 8720846
223 + 8720623 = 8720846
229 + 8720617 = 8720846
313 + 8720533 = 8720846

Showing the first eight; more decompositions exist.
