Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39520, here are decompositions:
- 11 + 39509 = 39520
- 17 + 39503 = 39520
- 59 + 39461 = 39520
- 101 + 39419 = 39520
- 137 + 39383 = 39520
- 149 + 39371 = 39520
- 179 + 39341 = 39520
- 197 + 39323 = 39520
Showing the first eight; more decompositions exist.
