Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9428, here are decompositions:
- 7 + 9421 = 9428
- 31 + 9397 = 9428
- 37 + 9391 = 9428
- 79 + 9349 = 9428
- 109 + 9319 = 9428
- 151 + 9277 = 9428
- 229 + 9199 = 9428
- 241 + 9187 = 9428
Showing the first eight; more decompositions exist.
