Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712470, here are decompositions:

73 + 8712397 = 8712470
97 + 8712373 = 8712470
103 + 8712367 = 8712470
163 + 8712307 = 8712470
211 + 8712259 = 8712470
241 + 8712229 = 8712470
307 + 8712163 = 8712470
313 + 8712157 = 8712470

Showing the first eight; more decompositions exist.
