Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30550, here are decompositions:
- 11 + 30539 = 30550
- 41 + 30509 = 30550
- 53 + 30497 = 30550
- 59 + 30491 = 30550
- 83 + 30467 = 30550
- 101 + 30449 = 30550
- 227 + 30323 = 30550
- 257 + 30293 = 30550
Showing the first eight; more decompositions exist.
