Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87368, here are decompositions:
- 31 + 87337 = 87368
- 157 + 87211 = 87368
- 181 + 87187 = 87368
- 331 + 87037 = 87368
- 409 + 86959 = 87368
- 439 + 86929 = 87368
- 499 + 86869 = 87368
- 601 + 86767 = 87368
Showing the first eight; more decompositions exist.
