Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636042, here are decompositions:

3 + 8636039 = 8636042
43 + 8635999 = 8636042
61 + 8635981 = 8636042
73 + 8635969 = 8636042
109 + 8635933 = 8636042
193 + 8635849 = 8636042
313 + 8635729 = 8636042
379 + 8635663 = 8636042

Showing the first eight; more decompositions exist.
