Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624042, here are decompositions:

19 + 8624023 = 8624042
73 + 8623969 = 8624042
79 + 8623963 = 8624042
103 + 8623939 = 8624042
139 + 8623903 = 8624042
199 + 8623843 = 8624042
211 + 8623831 = 8624042
241 + 8623801 = 8624042

Showing the first eight; more decompositions exist.
