Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28954, here are decompositions:
- 5 + 28949 = 28954
- 53 + 28901 = 28954
- 83 + 28871 = 28954
- 137 + 28817 = 28954
- 251 + 28703 = 28954
- 257 + 28697 = 28954
- 293 + 28661 = 28954
- 311 + 28643 = 28954
Showing the first eight; more decompositions exist.
