Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73428, here are decompositions:
- 7 + 73421 = 73428
- 11 + 73417 = 73428
- 41 + 73387 = 73428
- 59 + 73369 = 73428
- 67 + 73361 = 73428
- 97 + 73331 = 73428
- 101 + 73327 = 73428
- 137 + 73291 = 73428
Showing the first eight; more decompositions exist.
