Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743946, here are decompositions:

67 + 8743879 = 8743946
103 + 8743843 = 8743946
109 + 8743837 = 8743946
139 + 8743807 = 8743946
193 + 8743753 = 8743946
199 + 8743747 = 8743946
229 + 8743717 = 8743946
307 + 8743639 = 8743946

Showing the first eight; more decompositions exist.
