Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15758, here are decompositions:
- 19 + 15739 = 15758
- 31 + 15727 = 15758
- 79 + 15679 = 15758
- 97 + 15661 = 15758
- 109 + 15649 = 15758
- 139 + 15619 = 15758
- 151 + 15607 = 15758
- 157 + 15601 = 15758
Showing the first eight; more decompositions exist.
