Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744398, here are decompositions:

101 + 8744297 = 8744398
137 + 8744261 = 8744398
191 + 8744207 = 8744398
269 + 8744129 = 8744398
317 + 8744081 = 8744398
401 + 8743997 = 8744398
461 + 8743937 = 8744398
479 + 8743919 = 8744398

Showing the first eight; more decompositions exist.
