Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737178, here are decompositions:

61 + 8737117 = 8737178
67 + 8737111 = 8737178
139 + 8737039 = 8737178
157 + 8737021 = 8737178
271 + 8736907 = 8737178
379 + 8736799 = 8737178
397 + 8736781 = 8737178
547 + 8736631 = 8737178

Showing the first eight; more decompositions exist.
