Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80556, here are decompositions:
- 19 + 80537 = 80556
- 29 + 80527 = 80556
- 43 + 80513 = 80556
- 67 + 80489 = 80556
- 83 + 80473 = 80556
- 107 + 80449 = 80556
- 109 + 80447 = 80556
- 127 + 80429 = 80556
Showing the first eight; more decompositions exist.
