Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54920, here are decompositions:
- 3 + 54917 = 54920
- 13 + 54907 = 54920
- 43 + 54877 = 54920
- 193 + 54727 = 54920
- 199 + 54721 = 54920
- 211 + 54709 = 54920
- 241 + 54679 = 54920
- 337 + 54583 = 54920
Showing the first eight; more decompositions exist.
