Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86970, here are decompositions:
- 11 + 86959 = 86970
- 19 + 86951 = 86970
- 31 + 86939 = 86970
- 41 + 86929 = 86970
- 43 + 86927 = 86970
- 47 + 86923 = 86970
- 101 + 86869 = 86970
- 109 + 86861 = 86970
Showing the first eight; more decompositions exist.
