Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702126, here are decompositions:

19 + 8702107 = 8702126
127 + 8701999 = 8702126
193 + 8701933 = 8702126
313 + 8701813 = 8702126
337 + 8701789 = 8702126
379 + 8701747 = 8702126
397 + 8701729 = 8702126
607 + 8701519 = 8702126

Showing the first eight; more decompositions exist.
