Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73072, here are decompositions:
- 11 + 73061 = 73072
- 29 + 73043 = 73072
- 53 + 73019 = 73072
- 59 + 73013 = 73072
- 113 + 72959 = 73072
- 149 + 72923 = 73072
- 179 + 72893 = 73072
- 353 + 72719 = 73072
Showing the first eight; more decompositions exist.
