Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72998, here are decompositions:
- 61 + 72937 = 72998
- 67 + 72931 = 72998
- 97 + 72901 = 72998
- 109 + 72889 = 72998
- 127 + 72871 = 72998
- 139 + 72859 = 72998
- 181 + 72817 = 72998
- 271 + 72727 = 72998
Showing the first eight; more decompositions exist.
