Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635378, here are decompositions:

137 + 8635241 = 8635378
179 + 8635199 = 8635378
317 + 8635061 = 8635378
431 + 8634947 = 8635378
461 + 8634917 = 8635378
617 + 8634761 = 8635378
701 + 8634677 = 8635378
761 + 8634617 = 8635378

Showing the first eight; more decompositions exist.
