Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747912, here are decompositions:

109 + 8747803 = 8747912
211 + 8747701 = 8747912
223 + 8747689 = 8747912
373 + 8747539 = 8747912
661 + 8747251 = 8747912
829 + 8747083 = 8747912
991 + 8746921 = 8747912
1033 + 8746879 = 8747912

Showing the first eight; more decompositions exist.
