Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143912, here are decompositions:
- 3 + 143909 = 143912
- 31 + 143881 = 143912
- 79 + 143833 = 143912
- 193 + 143719 = 143912
- 283 + 143629 = 143912
- 409 + 143503 = 143912
- 499 + 143413 = 143912
- 631 + 143281 = 143912
Showing the first eight; more decompositions exist.
