Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138962, here are decompositions:
- 3 + 138959 = 138962
- 73 + 138889 = 138962
- 79 + 138883 = 138962
- 163 + 138799 = 138962
- 199 + 138763 = 138962
- 223 + 138739 = 138962
- 283 + 138679 = 138962
- 613 + 138349 = 138962
Showing the first eight; more decompositions exist.
