Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72716, here are decompositions:
- 37 + 72679 = 72716
- 43 + 72673 = 72716
- 67 + 72649 = 72716
- 73 + 72643 = 72716
- 103 + 72613 = 72716
- 139 + 72577 = 72716
- 157 + 72559 = 72716
- 223 + 72493 = 72716
Showing the first eight; more decompositions exist.
