Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87266, here are decompositions:
- 13 + 87253 = 87266
- 43 + 87223 = 87266
- 79 + 87187 = 87266
- 163 + 87103 = 87266
- 229 + 87037 = 87266
- 307 + 86959 = 87266
- 337 + 86929 = 87266
- 397 + 86869 = 87266
Showing the first eight; more decompositions exist.
