Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73440, here are decompositions:
- 7 + 73433 = 73440
- 19 + 73421 = 73440
- 23 + 73417 = 73440
- 53 + 73387 = 73440
- 61 + 73379 = 73440
- 71 + 73369 = 73440
- 79 + 73361 = 73440
- 89 + 73351 = 73440
Showing the first eight; more decompositions exist.
