Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87268, here are decompositions:
- 11 + 87257 = 87268
- 17 + 87251 = 87268
- 47 + 87221 = 87268
- 89 + 87179 = 87268
- 149 + 87119 = 87268
- 197 + 87071 = 87268
- 227 + 87041 = 87268
- 257 + 87011 = 87268
Showing the first eight; more decompositions exist.
