Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13628, here are decompositions:
- 31 + 13597 = 13628
- 37 + 13591 = 13628
- 61 + 13567 = 13628
- 151 + 13477 = 13628
- 211 + 13417 = 13628
- 229 + 13399 = 13628
- 331 + 13297 = 13628
- 337 + 13291 = 13628
Showing the first eight; more decompositions exist.
