Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744372, here are decompositions:

103 + 8744269 = 8744372
139 + 8744233 = 8744372
181 + 8744191 = 8744372
223 + 8744149 = 8744372
229 + 8744143 = 8744372
271 + 8744101 = 8744372
331 + 8744041 = 8744372
349 + 8744023 = 8744372

Showing the first eight; more decompositions exist.
