Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90768, here are decompositions:
- 19 + 90749 = 90768
- 37 + 90731 = 90768
- 59 + 90709 = 90768
- 71 + 90697 = 90768
- 89 + 90679 = 90768
- 109 + 90659 = 90768
- 127 + 90641 = 90768
- 137 + 90631 = 90768
Showing the first eight; more decompositions exist.
