Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709072, here are decompositions:
- 5 + 8709067 = 8709072
- 13 + 8709059 = 8709072
- 101 + 8708971 = 8709072
- 103 + 8708969 = 8709072
- 109 + 8708963 = 8709072
- 179 + 8708893 = 8709072
- 223 + 8708849 = 8709072
- 241 + 8708831 = 8709072
Showing the first eight; more decompositions exist.
