Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30406, here are decompositions:
- 3 + 30403 = 30406
- 17 + 30389 = 30406
- 59 + 30347 = 30406
- 83 + 30323 = 30406
- 113 + 30293 = 30406
- 137 + 30269 = 30406
- 269 + 30137 = 30406
- 293 + 30113 = 30406
Showing the first eight; more decompositions exist.
