Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635778, here are decompositions:

61 + 8635717 = 8635778
79 + 8635699 = 8635778
157 + 8635621 = 8635778
199 + 8635579 = 8635778
211 + 8635567 = 8635778
337 + 8635441 = 8635778
397 + 8635381 = 8635778
457 + 8635321 = 8635778

Showing the first eight; more decompositions exist.
