Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667242, here are decompositions:

139 + 8667103 = 8667242
163 + 8667079 = 8667242
379 + 8666863 = 8667242
433 + 8666809 = 8667242
709 + 8666533 = 8667242
751 + 8666491 = 8667242
811 + 8666431 = 8667242
823 + 8666419 = 8667242

Showing the first eight; more decompositions exist.
