Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13470, here are decompositions:
- 7 + 13463 = 13470
- 13 + 13457 = 13470
- 19 + 13451 = 13470
- 29 + 13441 = 13470
- 53 + 13417 = 13470
- 59 + 13411 = 13470
- 71 + 13399 = 13470
- 73 + 13397 = 13470
Showing the first eight; more decompositions exist.
