Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53940, here are decompositions:
- 13 + 53927 = 53940
- 17 + 53923 = 53940
- 23 + 53917 = 53940
- 41 + 53899 = 53940
- 43 + 53897 = 53940
- 53 + 53887 = 53940
- 59 + 53881 = 53940
- 79 + 53861 = 53940
Showing the first eight; more decompositions exist.
