Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30456, here are decompositions:
- 7 + 30449 = 30456
- 29 + 30427 = 30456
- 53 + 30403 = 30456
- 67 + 30389 = 30456
- 89 + 30367 = 30456
- 109 + 30347 = 30456
- 137 + 30319 = 30456
- 149 + 30307 = 30456
Showing the first eight; more decompositions exist.
