Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12672, here are decompositions:
- 13 + 12659 = 12672
- 19 + 12653 = 12672
- 31 + 12641 = 12672
- 53 + 12619 = 12672
- 59 + 12613 = 12672
- 61 + 12611 = 12672
- 71 + 12601 = 12672
- 83 + 12589 = 12672
Showing the first eight; more decompositions exist.
