Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761178, here are decompositions:

37 + 8761141 = 8761178
61 + 8761117 = 8761178
79 + 8761099 = 8761178
277 + 8760901 = 8761178
367 + 8760811 = 8761178
379 + 8760799 = 8761178
397 + 8760781 = 8761178
457 + 8760721 = 8761178

Showing the first eight; more decompositions exist.
