Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72404, here are decompositions:
- 37 + 72367 = 72404
- 67 + 72337 = 72404
- 97 + 72307 = 72404
- 127 + 72277 = 72404
- 151 + 72253 = 72404
- 181 + 72223 = 72404
- 193 + 72211 = 72404
- 313 + 72091 = 72404
Showing the first eight; more decompositions exist.
