Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30408, here are decompositions:
- 5 + 30403 = 30408
- 17 + 30391 = 30408
- 19 + 30389 = 30408
- 41 + 30367 = 30408
- 61 + 30347 = 30408
- 67 + 30341 = 30408
- 89 + 30319 = 30408
- 101 + 30307 = 30408
Showing the first eight; more decompositions exist.
