Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701982, here are decompositions:

31 + 8701951 = 8701982
61 + 8701921 = 8701982
109 + 8701873 = 8701982
193 + 8701789 = 8701982
241 + 8701741 = 8701982
463 + 8701519 = 8701982
661 + 8701321 = 8701982
673 + 8701309 = 8701982

Showing the first eight; more decompositions exist.
