Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720252, here are decompositions:

19 + 8720233 = 8720252
61 + 8720191 = 8720252
139 + 8720113 = 8720252
181 + 8720071 = 8720252
313 + 8719939 = 8720252
349 + 8719903 = 8720252
379 + 8719873 = 8720252
421 + 8719831 = 8720252

Showing the first eight; more decompositions exist.
