Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30664, here are decompositions:
- 3 + 30661 = 30664
- 71 + 30593 = 30664
- 107 + 30557 = 30664
- 167 + 30497 = 30664
- 173 + 30491 = 30664
- 197 + 30467 = 30664
- 233 + 30431 = 30664
- 317 + 30347 = 30664
Showing the first eight; more decompositions exist.
