Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87854, here are decompositions:
- 43 + 87811 = 87854
- 61 + 87793 = 87854
- 103 + 87751 = 87854
- 157 + 87697 = 87854
- 163 + 87691 = 87854
- 211 + 87643 = 87854
- 223 + 87631 = 87854
- 241 + 87613 = 87854
Showing the first eight; more decompositions exist.
