Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13478, here are decompositions:
- 37 + 13441 = 13478
- 61 + 13417 = 13478
- 67 + 13411 = 13478
- 79 + 13399 = 13478
- 97 + 13381 = 13478
- 139 + 13339 = 13478
- 151 + 13327 = 13478
- 181 + 13297 = 13478
Showing the first eight; more decompositions exist.
