Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12662, here are decompositions:
- 3 + 12659 = 12662
- 43 + 12619 = 12662
- 61 + 12601 = 12662
- 73 + 12589 = 12662
- 79 + 12583 = 12662
- 109 + 12553 = 12662
- 151 + 12511 = 12662
- 211 + 12451 = 12662
Showing the first eight; more decompositions exist.
