Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97020, here are decompositions:
- 13 + 97007 = 97020
- 17 + 97003 = 97020
- 19 + 97001 = 97020
- 23 + 96997 = 97020
- 31 + 96989 = 97020
- 41 + 96979 = 97020
- 47 + 96973 = 97020
- 61 + 96959 = 97020
Showing the first eight; more decompositions exist.
