Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701238, here are decompositions:

31 + 8701207 = 8701238
61 + 8701177 = 8701238
97 + 8701141 = 8701238
157 + 8701081 = 8701238
181 + 8701057 = 8701238
199 + 8701039 = 8701238
211 + 8701027 = 8701238
229 + 8701009 = 8701238

Showing the first eight; more decompositions exist.
