Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53990, here are decompositions:
- 3 + 53987 = 53990
- 31 + 53959 = 53990
- 67 + 53923 = 53990
- 73 + 53917 = 53990
- 103 + 53887 = 53990
- 109 + 53881 = 53990
- 199 + 53791 = 53990
- 271 + 53719 = 53990
Showing the first eight; more decompositions exist.
