Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91560, here are decompositions:
- 19 + 91541 = 91560
- 31 + 91529 = 91560
- 47 + 91513 = 91560
- 61 + 91499 = 91560
- 67 + 91493 = 91560
- 97 + 91463 = 91560
- 101 + 91459 = 91560
- 103 + 91457 = 91560
Showing the first eight; more decompositions exist.
