Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28434, here are decompositions:
- 5 + 28429 = 28434
- 23 + 28411 = 28434
- 31 + 28403 = 28434
- 41 + 28393 = 28434
- 47 + 28387 = 28434
- 83 + 28351 = 28434
- 127 + 28307 = 28434
- 137 + 28297 = 28434
Showing the first eight; more decompositions exist.
