Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66712, here are decompositions:
- 11 + 66701 = 66712
- 29 + 66683 = 66712
- 59 + 66653 = 66712
- 83 + 66629 = 66712
- 179 + 66533 = 66712
- 263 + 66449 = 66712
- 281 + 66431 = 66712
- 353 + 66359 = 66712
Showing the first eight; more decompositions exist.
