Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83428, here are decompositions:
- 5 + 83423 = 83428
- 11 + 83417 = 83428
- 29 + 83399 = 83428
- 71 + 83357 = 83428
- 89 + 83339 = 83428
- 197 + 83231 = 83428
- 251 + 83177 = 83428
- 311 + 83117 = 83428
Showing the first eight; more decompositions exist.
