Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143492, here are decompositions:
- 3 + 143489 = 143492
- 31 + 143461 = 143492
- 73 + 143419 = 143492
- 79 + 143413 = 143492
- 163 + 143329 = 143492
- 211 + 143281 = 143492
- 229 + 143263 = 143492
- 379 + 143113 = 143492
Showing the first eight; more decompositions exist.
