Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702540, here are decompositions:

37 + 8702503 = 8702540
43 + 8702497 = 8702540
109 + 8702431 = 8702540
181 + 8702359 = 8702540
199 + 8702341 = 8702540
211 + 8702329 = 8702540
229 + 8702311 = 8702540
367 + 8702173 = 8702540

Showing the first eight; more decompositions exist.
