Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149920, here are decompositions:
- 11 + 149909 = 149920
- 47 + 149873 = 149920
- 53 + 149867 = 149920
- 59 + 149861 = 149920
- 83 + 149837 = 149920
- 149 + 149771 = 149920
- 191 + 149729 = 149920
- 293 + 149627 = 149920
Showing the first eight; more decompositions exist.
