Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87024, here are decompositions:
- 11 + 87013 = 87024
- 13 + 87011 = 87024
- 31 + 86993 = 87024
- 43 + 86981 = 87024
- 73 + 86951 = 87024
- 97 + 86927 = 87024
- 101 + 86923 = 87024
- 163 + 86861 = 87024
Showing the first eight; more decompositions exist.
