Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73730, here are decompositions:
- 3 + 73727 = 73730
- 31 + 73699 = 73730
- 37 + 73693 = 73730
- 79 + 73651 = 73730
- 271 + 73459 = 73730
- 277 + 73453 = 73730
- 313 + 73417 = 73730
- 367 + 73363 = 73730
Showing the first eight; more decompositions exist.
