Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628242, here are decompositions:

61 + 8628181 = 8628242
193 + 8628049 = 8628242
211 + 8628031 = 8628242
223 + 8628019 = 8628242
331 + 8627911 = 8628242
349 + 8627893 = 8628242
409 + 8627833 = 8628242
433 + 8627809 = 8628242

Showing the first eight; more decompositions exist.
