Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72464, here are decompositions:
- 3 + 72461 = 72464
- 43 + 72421 = 72464
- 97 + 72367 = 72464
- 127 + 72337 = 72464
- 151 + 72313 = 72464
- 157 + 72307 = 72464
- 193 + 72271 = 72464
- 211 + 72253 = 72464
Showing the first eight; more decompositions exist.
