Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97920, here are decompositions:
- 37 + 97883 = 97920
- 41 + 97879 = 97920
- 59 + 97861 = 97920
- 61 + 97859 = 97920
- 71 + 97849 = 97920
- 73 + 97847 = 97920
- 79 + 97841 = 97920
- 107 + 97813 = 97920
Showing the first eight; more decompositions exist.
