Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77856, here are decompositions:
- 7 + 77849 = 77856
- 17 + 77839 = 77856
- 43 + 77813 = 77856
- 59 + 77797 = 77856
- 73 + 77783 = 77856
- 83 + 77773 = 77856
- 109 + 77747 = 77856
- 113 + 77743 = 77856
Showing the first eight; more decompositions exist.
