Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72426, here are decompositions:
- 5 + 72421 = 72426
- 43 + 72383 = 72426
- 47 + 72379 = 72426
- 59 + 72367 = 72426
- 73 + 72353 = 72426
- 89 + 72337 = 72426
- 113 + 72313 = 72426
- 139 + 72287 = 72426
Showing the first eight; more decompositions exist.
