Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697120, here are decompositions:
- 7 + 8697113 = 8697120
- 13 + 8697107 = 8697120
- 17 + 8697103 = 8697120
- 23 + 8697097 = 8697120
- 31 + 8697089 = 8697120
- 59 + 8697061 = 8697120
- 71 + 8697049 = 8697120
- 83 + 8697037 = 8697120
Showing the first eight; more decompositions exist.
