Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718080, here are decompositions:
- 37 + 8718043 = 8718080
- 67 + 8718013 = 8718080
- 73 + 8718007 = 8718080
- 199 + 8717881 = 8718080
- 211 + 8717869 = 8718080
- 223 + 8717857 = 8718080
- 271 + 8717809 = 8718080
- 277 + 8717803 = 8718080
Showing the first eight; more decompositions exist.
