Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87804, here are decompositions:
- 7 + 87797 = 87804
- 11 + 87793 = 87804
- 37 + 87767 = 87804
- 53 + 87751 = 87804
- 61 + 87743 = 87804
- 83 + 87721 = 87804
- 103 + 87701 = 87804
- 107 + 87697 = 87804
Showing the first eight; more decompositions exist.
