Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143390, here are decompositions:
- 3 + 143387 = 143390
- 61 + 143329 = 143390
- 103 + 143287 = 143390
- 109 + 143281 = 143390
- 127 + 143263 = 143390
- 151 + 143239 = 143390
- 193 + 143197 = 143390
- 277 + 143113 = 143390
Showing the first eight; more decompositions exist.
