Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 854, here are decompositions:
- 31 + 823 = 854
- 43 + 811 = 854
- 67 + 787 = 854
- 97 + 757 = 854
- 103 + 751 = 854
- 127 + 727 = 854
- 163 + 691 = 854
- 181 + 673 = 854
Showing the first eight; more decompositions exist.
