Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701312, here are decompositions:

3 + 8701309 = 8701312
23 + 8701289 = 8701312
41 + 8701271 = 8701312
101 + 8701211 = 8701312
149 + 8701163 = 8701312
311 + 8701001 = 8701312
359 + 8700953 = 8701312
401 + 8700911 = 8701312

Showing the first eight; more decompositions exist.
