Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701372, here are decompositions:

5 + 8701367 = 8701372
23 + 8701349 = 8701372
83 + 8701289 = 8701372
101 + 8701271 = 8701372
179 + 8701193 = 8701372
359 + 8701013 = 8701372
419 + 8700953 = 8701372
431 + 8700941 = 8701372

Showing the first eight; more decompositions exist.
