Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15962, here are decompositions:
- 3 + 15959 = 15962
- 43 + 15919 = 15962
- 61 + 15901 = 15962
- 73 + 15889 = 15962
- 103 + 15859 = 15962
- 139 + 15823 = 15962
- 223 + 15739 = 15962
- 229 + 15733 = 15962
Showing the first eight; more decompositions exist.
