Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64128, here are decompositions:
- 5 + 64123 = 64128
- 19 + 64109 = 64128
- 37 + 64091 = 64128
- 47 + 64081 = 64128
- 61 + 64067 = 64128
- 109 + 64019 = 64128
- 131 + 63997 = 64128
- 151 + 63977 = 64128
Showing the first eight; more decompositions exist.
