Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84428, here are decompositions:
- 7 + 84421 = 84428
- 37 + 84391 = 84428
- 79 + 84349 = 84428
- 109 + 84319 = 84428
- 181 + 84247 = 84428
- 199 + 84229 = 84428
- 229 + 84199 = 84428
- 307 + 84121 = 84428
Showing the first eight; more decompositions exist.
