Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86972, here are decompositions:
- 3 + 86969 = 86972
- 13 + 86959 = 86972
- 43 + 86929 = 86972
- 103 + 86869 = 86972
- 229 + 86743 = 86972
- 283 + 86689 = 86972
- 373 + 86599 = 86972
- 433 + 86539 = 86972
Showing the first eight; more decompositions exist.
