Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30450, here are decompositions:
- 19 + 30431 = 30450
- 23 + 30427 = 30450
- 47 + 30403 = 30450
- 59 + 30391 = 30450
- 61 + 30389 = 30450
- 83 + 30367 = 30450
- 103 + 30347 = 30450
- 109 + 30341 = 30450
Showing the first eight; more decompositions exist.
