Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28272, here are decompositions:
- 43 + 28229 = 28272
- 53 + 28219 = 28272
- 61 + 28211 = 28272
- 71 + 28201 = 28272
- 89 + 28183 = 28272
- 109 + 28163 = 28272
- 149 + 28123 = 28272
- 163 + 28109 = 28272
Showing the first eight; more decompositions exist.
