Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15366, here are decompositions:
- 5 + 15361 = 15366
- 7 + 15359 = 15366
- 17 + 15349 = 15366
- 37 + 15329 = 15366
- 47 + 15319 = 15366
- 53 + 15313 = 15366
- 59 + 15307 = 15366
- 67 + 15299 = 15366
Showing the first eight; more decompositions exist.
