Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73540, here are decompositions:
- 11 + 73529 = 73540
- 17 + 73523 = 73540
- 23 + 73517 = 73540
- 107 + 73433 = 73540
- 179 + 73361 = 73540
- 263 + 73277 = 73540
- 281 + 73259 = 73540
- 359 + 73181 = 73540
Showing the first eight; more decompositions exist.
