Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83578, here are decompositions:
- 17 + 83561 = 83578
- 41 + 83537 = 83578
- 101 + 83477 = 83578
- 107 + 83471 = 83578
- 179 + 83399 = 83578
- 239 + 83339 = 83578
- 311 + 83267 = 83578
- 347 + 83231 = 83578
Showing the first eight; more decompositions exist.
