Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718444, here are decompositions:
- 5 + 8718439 = 8718444
- 13 + 8718431 = 8718444
- 17 + 8718427 = 8718444
- 37 + 8718407 = 8718444
- 43 + 8718401 = 8718444
- 67 + 8718377 = 8718444
- 101 + 8718343 = 8718444
- 131 + 8718313 = 8718444
Showing the first eight; more decompositions exist.
