Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707388, here are decompositions:

31 + 8707357 = 8707388
37 + 8707351 = 8707388
61 + 8707327 = 8707388
181 + 8707207 = 8707388
199 + 8707189 = 8707388
229 + 8707159 = 8707388
241 + 8707147 = 8707388
331 + 8707057 = 8707388

Showing the first eight; more decompositions exist.
