Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744390, here are decompositions:

73 + 8744317 = 8744390
157 + 8744233 = 8744390
163 + 8744227 = 8744390
199 + 8744191 = 8744390
241 + 8744149 = 8744390
307 + 8744083 = 8744390
349 + 8744041 = 8744390
367 + 8744023 = 8744390

Showing the first eight; more decompositions exist.
