Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725574, here are decompositions:

3 + 8725571 = 8725574
7 + 8725567 = 8725574
43 + 8725531 = 8725574
211 + 8725363 = 8725574
331 + 8725243 = 8725574
367 + 8725207 = 8725574
397 + 8725177 = 8725574
421 + 8725153 = 8725574

Showing the first eight; more decompositions exist.
