Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720470, here are decompositions:

23 + 8720447 = 8720470
41 + 8720429 = 8720470
53 + 8720417 = 8720470
131 + 8720339 = 8720470
149 + 8720321 = 8720470
281 + 8720189 = 8720470
293 + 8720177 = 8720470
359 + 8720111 = 8720470

Showing the first eight; more decompositions exist.
