Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87068, here are decompositions:
- 19 + 87049 = 87068
- 31 + 87037 = 87068
- 109 + 86959 = 87068
- 139 + 86929 = 87068
- 199 + 86869 = 87068
- 211 + 86857 = 87068
- 349 + 86719 = 87068
- 379 + 86689 = 87068
Showing the first eight; more decompositions exist.
