Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13472, here are decompositions:
- 3 + 13469 = 13472
- 31 + 13441 = 13472
- 61 + 13411 = 13472
- 73 + 13399 = 13472
- 163 + 13309 = 13472
- 181 + 13291 = 13472
- 223 + 13249 = 13472
- 313 + 13159 = 13472
Showing the first eight; more decompositions exist.
