Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28276, here are decompositions:
- 47 + 28229 = 28276
- 113 + 28163 = 28276
- 167 + 28109 = 28276
- 179 + 28097 = 28276
- 257 + 28019 = 28276
- 293 + 27983 = 28276
- 359 + 27917 = 28276
- 383 + 27893 = 28276
Showing the first eight; more decompositions exist.
