Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4428, here are decompositions:
- 5 + 4423 = 4428
- 7 + 4421 = 4428
- 19 + 4409 = 4428
- 31 + 4397 = 4428
- 37 + 4391 = 4428
- 71 + 4357 = 4428
- 79 + 4349 = 4428
- 89 + 4339 = 4428
Showing the first eight; more decompositions exist.
