Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747122, here are decompositions:

3 + 8747119 = 8747122
11 + 8747111 = 8747122
29 + 8747093 = 8747122
173 + 8746949 = 8747122
311 + 8746811 = 8747122
389 + 8746733 = 8747122
443 + 8746679 = 8747122
653 + 8746469 = 8747122

Showing the first eight; more decompositions exist.
