Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55920, here are decompositions:
- 17 + 55903 = 55920
- 19 + 55901 = 55920
- 23 + 55897 = 55920
- 31 + 55889 = 55920
- 71 + 55849 = 55920
- 83 + 55837 = 55920
- 97 + 55823 = 55920
- 101 + 55819 = 55920
Showing the first eight; more decompositions exist.
