Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73518, here are decompositions:
- 41 + 73477 = 73518
- 47 + 73471 = 73518
- 59 + 73459 = 73518
- 97 + 73421 = 73518
- 101 + 73417 = 73518
- 131 + 73387 = 73518
- 139 + 73379 = 73518
- 149 + 73369 = 73518
Showing the first eight; more decompositions exist.
