Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91022, here are decompositions:
- 3 + 91019 = 91022
- 13 + 91009 = 91022
- 181 + 90841 = 91022
- 199 + 90823 = 91022
- 229 + 90793 = 91022
- 313 + 90709 = 91022
- 439 + 90583 = 91022
- 499 + 90523 = 91022
Showing the first eight; more decompositions exist.
