Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702120, here are decompositions:

13 + 8702107 = 8702120
199 + 8701921 = 8702120
307 + 8701813 = 8702120
331 + 8701789 = 8702120
373 + 8701747 = 8702120
379 + 8701741 = 8702120
397 + 8701723 = 8702120
463 + 8701657 = 8702120

Showing the first eight; more decompositions exist.
