Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87300, here are decompositions:
- 7 + 87293 = 87300
- 19 + 87281 = 87300
- 23 + 87277 = 87300
- 43 + 87257 = 87300
- 47 + 87253 = 87300
- 79 + 87221 = 87300
- 89 + 87211 = 87300
- 113 + 87187 = 87300
Showing the first eight; more decompositions exist.
