Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009972, here are decompositions:
- 71 + 1009901 = 1009972
- 113 + 1009859 = 1009972
- 191 + 1009781 = 1009972
- 599 + 1009373 = 1009972
- 653 + 1009319 = 1009972
- 683 + 1009289 = 1009972
- 773 + 1009199 = 1009972
- 809 + 1009163 = 1009972
Showing the first eight; more decompositions exist.
