Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87084, here are decompositions:
- 13 + 87071 = 87084
- 43 + 87041 = 87084
- 47 + 87037 = 87084
- 71 + 87013 = 87084
- 73 + 87011 = 87084
- 103 + 86981 = 87084
- 157 + 86927 = 87084
- 223 + 86861 = 87084
Showing the first eight; more decompositions exist.
