Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649042, here are decompositions:

13 + 8649029 = 8649042
19 + 8649023 = 8649042
41 + 8649001 = 8649042
89 + 8648953 = 8649042
113 + 8648929 = 8649042
163 + 8648879 = 8649042
179 + 8648863 = 8649042
211 + 8648831 = 8649042

Showing the first eight; more decompositions exist.
