Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87408, here are decompositions:
- 5 + 87403 = 87408
- 71 + 87337 = 87408
- 109 + 87299 = 87408
- 127 + 87281 = 87408
- 131 + 87277 = 87408
- 151 + 87257 = 87408
- 157 + 87251 = 87408
- 197 + 87211 = 87408
Showing the first eight; more decompositions exist.
