Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720332, here are decompositions:

11 + 8720321 = 8720332
251 + 8720081 = 8720332
389 + 8719943 = 8720332
911 + 8719421 = 8720332
941 + 8719391 = 8720332
953 + 8719379 = 8720332
983 + 8719349 = 8720332
1031 + 8719301 = 8720332

Showing the first eight; more decompositions exist.
