Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80560, here are decompositions:
- 3 + 80557 = 80560
- 23 + 80537 = 80560
- 47 + 80513 = 80560
- 71 + 80489 = 80560
- 89 + 80471 = 80560
- 113 + 80447 = 80560
- 131 + 80429 = 80560
- 173 + 80387 = 80560
Showing the first eight; more decompositions exist.
