Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87838, here are decompositions:
- 5 + 87833 = 87838
- 41 + 87797 = 87838
- 71 + 87767 = 87838
- 137 + 87701 = 87838
- 167 + 87671 = 87838
- 197 + 87641 = 87838
- 251 + 87587 = 87838
- 281 + 87557 = 87838
Showing the first eight; more decompositions exist.
