Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709888, here are decompositions:
- 17 + 8709871 = 8709888
- 67 + 8709821 = 8709888
- 71 + 8709817 = 8709888
- 107 + 8709781 = 8709888
- 137 + 8709751 = 8709888
- 151 + 8709737 = 8709888
- 157 + 8709731 = 8709888
- 167 + 8709721 = 8709888
Showing the first eight; more decompositions exist.
