Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87876, here are decompositions:
- 7 + 87869 = 87876
- 23 + 87853 = 87876
- 43 + 87833 = 87876
- 73 + 87803 = 87876
- 79 + 87797 = 87876
- 83 + 87793 = 87876
- 109 + 87767 = 87876
- 137 + 87739 = 87876
Showing the first eight; more decompositions exist.
