Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87116, here are decompositions:
- 13 + 87103 = 87116
- 67 + 87049 = 87116
- 79 + 87037 = 87116
- 103 + 87013 = 87116
- 157 + 86959 = 87116
- 193 + 86923 = 87116
- 349 + 86767 = 87116
- 373 + 86743 = 87116
Showing the first eight; more decompositions exist.
