Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87316, here are decompositions:
- 3 + 87313 = 87316
- 17 + 87299 = 87316
- 23 + 87293 = 87316
- 59 + 87257 = 87316
- 137 + 87179 = 87316
- 167 + 87149 = 87316
- 197 + 87119 = 87316
- 233 + 87083 = 87316
Showing the first eight; more decompositions exist.
