Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997572, here are decompositions:
- 19 + 997553 = 997572
- 31 + 997541 = 997572
- 61 + 997511 = 997572
- 109 + 997463 = 997572
- 139 + 997433 = 997572
- 181 + 997391 = 997572
- 193 + 997379 = 997572
- 229 + 997343 = 997572
Showing the first eight; more decompositions exist.
