Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5428, here are decompositions:
- 11 + 5417 = 5428
- 29 + 5399 = 5428
- 41 + 5387 = 5428
- 47 + 5381 = 5428
- 131 + 5297 = 5428
- 149 + 5279 = 5428
- 167 + 5261 = 5428
- 191 + 5237 = 5428
Showing the first eight; more decompositions exist.
