Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15694, here are decompositions:
- 11 + 15683 = 15694
- 23 + 15671 = 15694
- 47 + 15647 = 15694
- 53 + 15641 = 15694
- 113 + 15581 = 15694
- 167 + 15527 = 15694
- 197 + 15497 = 15694
- 227 + 15467 = 15694
Showing the first eight; more decompositions exist.
