Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635042, here are decompositions:

71 + 8634971 = 8635042
179 + 8634863 = 8635042
191 + 8634851 = 8635042
239 + 8634803 = 8635042
281 + 8634761 = 8635042
461 + 8634581 = 8635042
491 + 8634551 = 8635042
503 + 8634539 = 8635042

Showing the first eight; more decompositions exist.
