Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87124, here are decompositions:
- 3 + 87121 = 87124
- 5 + 87119 = 87124
- 17 + 87107 = 87124
- 41 + 87083 = 87124
- 53 + 87071 = 87124
- 83 + 87041 = 87124
- 113 + 87011 = 87124
- 131 + 86993 = 87124
Showing the first eight; more decompositions exist.
