Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30712, here are decompositions:
- 5 + 30707 = 30712
- 23 + 30689 = 30712
- 41 + 30671 = 30712
- 173 + 30539 = 30712
- 263 + 30449 = 30712
- 281 + 30431 = 30712
- 389 + 30323 = 30712
- 419 + 30293 = 30712
Showing the first eight; more decompositions exist.
