Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744186, here are decompositions:

37 + 8744149 = 8744186
43 + 8744143 = 8744186
103 + 8744083 = 8744186
163 + 8744023 = 8744186
223 + 8743963 = 8744186
307 + 8743879 = 8744186
349 + 8743837 = 8744186
379 + 8743807 = 8744186

Showing the first eight; more decompositions exist.
