Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78772, here are decompositions:
- 59 + 78713 = 78772
- 149 + 78623 = 78772
- 179 + 78593 = 78772
- 233 + 78539 = 78772
- 263 + 78509 = 78772
- 293 + 78479 = 78772
- 431 + 78341 = 78772
- 461 + 78311 = 78772
Showing the first eight; more decompositions exist.
