Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30644, here are decompositions:
- 7 + 30637 = 30644
- 13 + 30631 = 30644
- 67 + 30577 = 30644
- 127 + 30517 = 30644
- 151 + 30493 = 30644
- 241 + 30403 = 30644
- 277 + 30367 = 30644
- 331 + 30313 = 30644
Showing the first eight; more decompositions exist.
