Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743904, here are decompositions:

3 + 8743901 = 8743904
61 + 8743843 = 8743904
67 + 8743837 = 8743904
97 + 8743807 = 8743904
151 + 8743753 = 8743904
157 + 8743747 = 8743904
193 + 8743711 = 8743904
223 + 8743681 = 8743904

Showing the first eight; more decompositions exist.
