Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15378, here are decompositions:
- 5 + 15373 = 15378
- 17 + 15361 = 15378
- 19 + 15359 = 15378
- 29 + 15349 = 15378
- 47 + 15331 = 15378
- 59 + 15319 = 15378
- 71 + 15307 = 15378
- 79 + 15299 = 15378
Showing the first eight; more decompositions exist.
