Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86878, here are decompositions:
- 17 + 86861 = 86878
- 41 + 86837 = 86878
- 107 + 86771 = 86878
- 149 + 86729 = 86878
- 167 + 86711 = 86878
- 251 + 86627 = 86878
- 317 + 86561 = 86878
- 347 + 86531 = 86878
Showing the first eight; more decompositions exist.
