Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87006, here are decompositions:
- 13 + 86993 = 87006
- 37 + 86969 = 87006
- 47 + 86959 = 87006
- 67 + 86939 = 87006
- 79 + 86927 = 87006
- 83 + 86923 = 87006
- 137 + 86869 = 87006
- 149 + 86857 = 87006
Showing the first eight; more decompositions exist.
