Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87108, here are decompositions:
- 5 + 87103 = 87108
- 37 + 87071 = 87108
- 59 + 87049 = 87108
- 67 + 87041 = 87108
- 71 + 87037 = 87108
- 97 + 87011 = 87108
- 127 + 86981 = 87108
- 139 + 86969 = 87108
Showing the first eight; more decompositions exist.
