Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13550, here are decompositions:
- 13 + 13537 = 13550
- 37 + 13513 = 13550
- 73 + 13477 = 13550
- 109 + 13441 = 13550
- 139 + 13411 = 13550
- 151 + 13399 = 13550
- 211 + 13339 = 13550
- 223 + 13327 = 13550
Showing the first eight; more decompositions exist.
