Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140128, here are decompositions:
- 5 + 140123 = 140128
- 17 + 140111 = 140128
- 59 + 140069 = 140128
- 71 + 140057 = 140128
- 137 + 139991 = 140128
- 227 + 139901 = 140128
- 257 + 139871 = 140128
- 389 + 139739 = 140128
Showing the first eight; more decompositions exist.
