Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87134, here are decompositions:
- 13 + 87121 = 87134
- 31 + 87103 = 87134
- 97 + 87037 = 87134
- 211 + 86923 = 87134
- 277 + 86857 = 87134
- 283 + 86851 = 87134
- 367 + 86767 = 87134
- 457 + 86677 = 87134
Showing the first eight; more decompositions exist.
