Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731570, here are decompositions:

41 + 8731529 = 8731570
59 + 8731511 = 8731570
137 + 8731433 = 8731570
227 + 8731343 = 8731570
257 + 8731313 = 8731570
269 + 8731301 = 8731570
293 + 8731277 = 8731570
359 + 8731211 = 8731570

Showing the first eight; more decompositions exist.
