Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725532, here are decompositions:

43 + 8725489 = 8725532
73 + 8725459 = 8725532
103 + 8725429 = 8725532
313 + 8725219 = 8725532
349 + 8725183 = 8725532
373 + 8725159 = 8725532
379 + 8725153 = 8725532
421 + 8725111 = 8725532

Showing the first eight; more decompositions exist.
