Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52140, here are decompositions:
- 13 + 52127 = 52140
- 19 + 52121 = 52140
- 37 + 52103 = 52140
- 59 + 52081 = 52140
- 71 + 52069 = 52140
- 73 + 52067 = 52140
- 83 + 52057 = 52140
- 89 + 52051 = 52140
Showing the first eight; more decompositions exist.
