Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725748, here are decompositions:

67 + 8725681 = 8725748
79 + 8725669 = 8725748
127 + 8725621 = 8725748
139 + 8725609 = 8725748
181 + 8725567 = 8725748
349 + 8725399 = 8725748
541 + 8725207 = 8725748
571 + 8725177 = 8725748

Showing the first eight; more decompositions exist.
