Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747132, here are decompositions:

13 + 8747119 = 8747132
61 + 8747071 = 8747132
193 + 8746939 = 8747132
211 + 8746921 = 8747132
271 + 8746861 = 8747132
283 + 8746849 = 8747132
313 + 8746819 = 8747132
379 + 8746753 = 8747132

Showing the first eight; more decompositions exist.
