Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86840, here are decompositions:
- 3 + 86837 = 86840
- 73 + 86767 = 86840
- 97 + 86743 = 86840
- 151 + 86689 = 86840
- 163 + 86677 = 86840
- 211 + 86629 = 86840
- 241 + 86599 = 86840
- 307 + 86533 = 86840
Showing the first eight; more decompositions exist.
