Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143392, here are decompositions:
- 5 + 143387 = 143392
- 59 + 143333 = 143392
- 101 + 143291 = 143392
- 131 + 143261 = 143392
- 149 + 143243 = 143392
- 233 + 143159 = 143392
- 251 + 143141 = 143392
- 281 + 143111 = 143392
Showing the first eight; more decompositions exist.
