Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91428, here are decompositions:
- 5 + 91423 = 91428
- 17 + 91411 = 91428
- 31 + 91397 = 91428
- 41 + 91387 = 91428
- 47 + 91381 = 91428
- 59 + 91369 = 91428
- 61 + 91367 = 91428
- 97 + 91331 = 91428
Showing the first eight; more decompositions exist.
