Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13272, here are decompositions:
- 5 + 13267 = 13272
- 13 + 13259 = 13272
- 23 + 13249 = 13272
- 31 + 13241 = 13272
- 43 + 13229 = 13272
- 53 + 13219 = 13272
- 89 + 13183 = 13272
- 101 + 13171 = 13272
Showing the first eight; more decompositions exist.
