Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747126, here are decompositions:

7 + 8747119 = 8747126
43 + 8747083 = 8747126
127 + 8746999 = 8747126
163 + 8746963 = 8747126
277 + 8746849 = 8747126
307 + 8746819 = 8747126
313 + 8746813 = 8747126
373 + 8746753 = 8747126

Showing the first eight; more decompositions exist.
