Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87002, here are decompositions:
- 43 + 86959 = 87002
- 73 + 86929 = 87002
- 79 + 86923 = 87002
- 151 + 86851 = 87002
- 283 + 86719 = 87002
- 313 + 86689 = 87002
- 373 + 86629 = 87002
- 463 + 86539 = 87002
Showing the first eight; more decompositions exist.
