Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701172, here are decompositions:

31 + 8701141 = 8701172
163 + 8701009 = 8701172
241 + 8700931 = 8701172
373 + 8700799 = 8701172
379 + 8700793 = 8701172
421 + 8700751 = 8701172
463 + 8700709 = 8701172
523 + 8700649 = 8701172

Showing the first eight; more decompositions exist.
