Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28424, here are decompositions:
- 13 + 28411 = 28424
- 31 + 28393 = 28424
- 37 + 28387 = 28424
- 73 + 28351 = 28424
- 127 + 28297 = 28424
- 223 + 28201 = 28424
- 241 + 28183 = 28424
- 313 + 28111 = 28424
Showing the first eight; more decompositions exist.
