Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997072, here are decompositions:
- 3 + 997069 = 997072
- 29 + 997043 = 997072
- 53 + 997019 = 997072
- 59 + 997013 = 997072
- 71 + 997001 = 997072
- 173 + 996899 = 997072
- 191 + 996881 = 997072
- 269 + 996803 = 997072
Showing the first eight; more decompositions exist.
