Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131376, here are decompositions:
- 5 + 131371 = 131376
- 13 + 131363 = 131376
- 19 + 131357 = 131376
- 59 + 131317 = 131376
- 73 + 131303 = 131376
- 79 + 131297 = 131376
- 83 + 131293 = 131376
- 109 + 131267 = 131376
Showing the first eight; more decompositions exist.
