Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86940, here are decompositions:
- 11 + 86929 = 86940
- 13 + 86927 = 86940
- 17 + 86923 = 86940
- 71 + 86869 = 86940
- 79 + 86861 = 86940
- 83 + 86857 = 86940
- 89 + 86851 = 86940
- 97 + 86843 = 86940
Showing the first eight; more decompositions exist.
