Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143618, here are decompositions:
- 67 + 143551 = 143618
- 109 + 143509 = 143618
- 151 + 143467 = 143618
- 157 + 143461 = 143618
- 199 + 143419 = 143618
- 331 + 143287 = 143618
- 337 + 143281 = 143618
- 379 + 143239 = 143618
Showing the first eight; more decompositions exist.
