Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725784, here are decompositions:

103 + 8725681 = 8725784
127 + 8725657 = 8725784
157 + 8725627 = 8725784
163 + 8725621 = 8725784
421 + 8725363 = 8725784
541 + 8725243 = 8725784
577 + 8725207 = 8725784
601 + 8725183 = 8725784

Showing the first eight; more decompositions exist.
