Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51538, here are decompositions:
- 17 + 51521 = 51538
- 59 + 51479 = 51538
- 89 + 51449 = 51538
- 101 + 51437 = 51538
- 107 + 51431 = 51538
- 131 + 51407 = 51538
- 191 + 51347 = 51538
- 197 + 51341 = 51538
Showing the first eight; more decompositions exist.
