Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701178, here are decompositions:

37 + 8701141 = 8701178
61 + 8701117 = 8701178
97 + 8701081 = 8701178
139 + 8701039 = 8701178
151 + 8701027 = 8701178
307 + 8700871 = 8701178
379 + 8700799 = 8701178
457 + 8700721 = 8701178

Showing the first eight; more decompositions exist.
