Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15426, here are decompositions:
- 13 + 15413 = 15426
- 43 + 15383 = 15426
- 53 + 15373 = 15426
- 67 + 15359 = 15426
- 97 + 15329 = 15426
- 107 + 15319 = 15426
- 113 + 15313 = 15426
- 127 + 15299 = 15426
Showing the first eight; more decompositions exist.
