Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720882, here are decompositions:

43 + 8720839 = 8720882
73 + 8720809 = 8720882
109 + 8720773 = 8720882
193 + 8720689 = 8720882
211 + 8720671 = 8720882
349 + 8720533 = 8720882
571 + 8720311 = 8720882
601 + 8720281 = 8720882

Showing the first eight; more decompositions exist.
