Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12612, here are decompositions:
- 11 + 12601 = 12612
- 23 + 12589 = 12612
- 29 + 12583 = 12612
- 43 + 12569 = 12612
- 59 + 12553 = 12612
- 71 + 12541 = 12612
- 73 + 12539 = 12612
- 101 + 12511 = 12612
Showing the first eight; more decompositions exist.
