Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73040, here are decompositions:
- 3 + 73037 = 73040
- 31 + 73009 = 73040
- 43 + 72997 = 73040
- 67 + 72973 = 73040
- 103 + 72937 = 73040
- 109 + 72931 = 73040
- 139 + 72901 = 73040
- 151 + 72889 = 73040
Showing the first eight; more decompositions exist.
