Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15718, here are decompositions:
- 47 + 15671 = 15718
- 71 + 15647 = 15718
- 89 + 15629 = 15718
- 137 + 15581 = 15718
- 149 + 15569 = 15718
- 167 + 15551 = 15718
- 191 + 15527 = 15718
- 251 + 15467 = 15718
Showing the first eight; more decompositions exist.
