Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725040, here are decompositions:

3 + 8725037 = 8725040
19 + 8725021 = 8725040
73 + 8724967 = 8725040
97 + 8724943 = 8725040
157 + 8724883 = 8725040
193 + 8724847 = 8725040
241 + 8724799 = 8725040
397 + 8724643 = 8725040

Showing the first eight; more decompositions exist.
