Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5578, here are decompositions:
- 5 + 5573 = 5578
- 47 + 5531 = 5578
- 59 + 5519 = 5578
- 71 + 5507 = 5578
- 101 + 5477 = 5578
- 107 + 5471 = 5578
- 137 + 5441 = 5578
- 179 + 5399 = 5578
Showing the first eight; more decompositions exist.
