Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30772, here are decompositions:
- 59 + 30713 = 30772
- 83 + 30689 = 30772
- 101 + 30671 = 30772
- 179 + 30593 = 30772
- 233 + 30539 = 30772
- 263 + 30509 = 30772
- 281 + 30491 = 30772
- 383 + 30389 = 30772
Showing the first eight; more decompositions exist.
