Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30438, here are decompositions:
- 7 + 30431 = 30438
- 11 + 30427 = 30438
- 47 + 30391 = 30438
- 71 + 30367 = 30438
- 97 + 30341 = 30438
- 131 + 30307 = 30438
- 167 + 30271 = 30438
- 179 + 30259 = 30438
Showing the first eight; more decompositions exist.
