Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997620, here are decompositions:
- 11 + 997609 = 997620
- 23 + 997597 = 997620
- 31 + 997589 = 997620
- 37 + 997583 = 997620
- 47 + 997573 = 997620
- 67 + 997553 = 997620
- 73 + 997547 = 997620
- 79 + 997541 = 997620
Showing the first eight; more decompositions exist.
