Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87298, here are decompositions:
- 5 + 87293 = 87298
- 17 + 87281 = 87298
- 41 + 87257 = 87298
- 47 + 87251 = 87298
- 149 + 87149 = 87298
- 179 + 87119 = 87298
- 191 + 87107 = 87298
- 227 + 87071 = 87298
Showing the first eight; more decompositions exist.
