Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720032, here are decompositions:

5 + 8720027 = 8720032
71 + 8719961 = 8720032
89 + 8719943 = 8720032
491 + 8719541 = 8720032
641 + 8719391 = 8720032
653 + 8719379 = 8720032
683 + 8719349 = 8720032
743 + 8719289 = 8720032

Showing the first eight; more decompositions exist.
