Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13672, here are decompositions:
- 3 + 13669 = 13672
- 23 + 13649 = 13672
- 53 + 13619 = 13672
- 59 + 13613 = 13672
- 149 + 13523 = 13672
- 173 + 13499 = 13672
- 251 + 13421 = 13672
- 359 + 13313 = 13672
Showing the first eight; more decompositions exist.
