Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701874, here are decompositions:

3 + 8701871 = 8701874
61 + 8701813 = 8701874
127 + 8701747 = 8701874
151 + 8701723 = 8701874
367 + 8701507 = 8701874
397 + 8701477 = 8701874
607 + 8701267 = 8701874
631 + 8701243 = 8701874

Showing the first eight; more decompositions exist.
