Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45512, here are decompositions:
- 31 + 45481 = 45512
- 73 + 45439 = 45512
- 79 + 45433 = 45512
- 109 + 45403 = 45512
- 151 + 45361 = 45512
- 193 + 45319 = 45512
- 223 + 45289 = 45512
- 331 + 45181 = 45512
Showing the first eight; more decompositions exist.
