Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743880, here are decompositions:

37 + 8743843 = 8743880
43 + 8743837 = 8743880
73 + 8743807 = 8743880
109 + 8743771 = 8743880
127 + 8743753 = 8743880
163 + 8743717 = 8743880
199 + 8743681 = 8743880
241 + 8743639 = 8743880

Showing the first eight; more decompositions exist.
