Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743940, here are decompositions:

3 + 8743937 = 8743940
61 + 8743879 = 8743940
97 + 8743843 = 8743940
103 + 8743837 = 8743940
193 + 8743747 = 8743940
223 + 8743717 = 8743940
229 + 8743711 = 8743940
307 + 8743633 = 8743940

Showing the first eight; more decompositions exist.
