Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744428, here are decompositions:
- 5 + 8744423 = 8744428
- 131 + 8744297 = 8744428
- 167 + 8744261 = 8744428
- 239 + 8744189 = 8744428
- 347 + 8744081 = 8744428
- 431 + 8743997 = 8744428
- 491 + 8743937 = 8744428
- 509 + 8743919 = 8744428
Showing the first eight; more decompositions exist.
