Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30378, here are decompositions:
- 11 + 30367 = 30378
- 31 + 30347 = 30378
- 37 + 30341 = 30378
- 59 + 30319 = 30378
- 71 + 30307 = 30378
- 107 + 30271 = 30378
- 109 + 30269 = 30378
- 137 + 30241 = 30378
Showing the first eight; more decompositions exist.
