Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87850, here are decompositions:
- 17 + 87833 = 87850
- 47 + 87803 = 87850
- 53 + 87797 = 87850
- 83 + 87767 = 87850
- 107 + 87743 = 87850
- 131 + 87719 = 87850
- 149 + 87701 = 87850
- 167 + 87683 = 87850
Showing the first eight; more decompositions exist.
