Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997272, here are decompositions:
- 5 + 997267 = 997272
- 13 + 997259 = 997272
- 53 + 997219 = 997272
- 71 + 997201 = 997272
- 109 + 997163 = 997272
- 131 + 997141 = 997272
- 149 + 997123 = 997272
- 151 + 997121 = 997272
Showing the first eight; more decompositions exist.
