Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15386, here are decompositions:
- 3 + 15383 = 15386
- 13 + 15373 = 15386
- 37 + 15349 = 15386
- 67 + 15319 = 15386
- 73 + 15313 = 15386
- 79 + 15307 = 15386
- 97 + 15289 = 15386
- 109 + 15277 = 15386
Showing the first eight; more decompositions exist.
