Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86990, here are decompositions:
- 31 + 86959 = 86990
- 61 + 86929 = 86990
- 67 + 86923 = 86990
- 139 + 86851 = 86990
- 223 + 86767 = 86990
- 271 + 86719 = 86990
- 313 + 86677 = 86990
- 457 + 86533 = 86990
Showing the first eight; more decompositions exist.
