Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745408, here are decompositions:
- 41 + 8745367 = 8745408
- 79 + 8745329 = 8745408
- 97 + 8745311 = 8745408
- 101 + 8745307 = 8745408
- 109 + 8745299 = 8745408
- 167 + 8745241 = 8745408
- 181 + 8745227 = 8745408
- 239 + 8745169 = 8745408
Showing the first eight; more decompositions exist.
