Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635478, here are decompositions:

37 + 8635441 = 8635478
97 + 8635381 = 8635478
127 + 8635351 = 8635478
157 + 8635321 = 8635478
199 + 8635279 = 8635478
337 + 8635141 = 8635478
421 + 8635057 = 8635478
457 + 8635021 = 8635478

Showing the first eight; more decompositions exist.
