Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87008, here are decompositions:
- 79 + 86929 = 87008
- 139 + 86869 = 87008
- 151 + 86857 = 87008
- 157 + 86851 = 87008
- 241 + 86767 = 87008
- 331 + 86677 = 87008
- 379 + 86629 = 87008
- 409 + 86599 = 87008
Showing the first eight; more decompositions exist.
