Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15746, here are decompositions:
- 7 + 15739 = 15746
- 13 + 15733 = 15746
- 19 + 15727 = 15746
- 67 + 15679 = 15746
- 79 + 15667 = 15746
- 97 + 15649 = 15746
- 103 + 15643 = 15746
- 127 + 15619 = 15746
Showing the first eight; more decompositions exist.
