Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15356, here are decompositions:
- 7 + 15349 = 15356
- 37 + 15319 = 15356
- 43 + 15313 = 15356
- 67 + 15289 = 15356
- 79 + 15277 = 15356
- 97 + 15259 = 15356
- 139 + 15217 = 15356
- 157 + 15199 = 15356
Showing the first eight; more decompositions exist.
