Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744220, here are decompositions:
- 13 + 8744207 = 8744220
- 29 + 8744191 = 8744220
- 31 + 8744189 = 8744220
- 71 + 8744149 = 8744220
- 137 + 8744083 = 8744220
- 139 + 8744081 = 8744220
- 157 + 8744063 = 8744220
- 179 + 8744041 = 8744220
Showing the first eight; more decompositions exist.
