Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85790, here are decompositions:
- 73 + 85717 = 85790
- 79 + 85711 = 85790
- 151 + 85639 = 85790
- 163 + 85627 = 85790
- 193 + 85597 = 85790
- 241 + 85549 = 85790
- 277 + 85513 = 85790
- 337 + 85453 = 85790
Showing the first eight; more decompositions exist.
