Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97980, here are decompositions:
- 7 + 97973 = 97980
- 13 + 97967 = 97980
- 19 + 97961 = 97980
- 37 + 97943 = 97980
- 53 + 97927 = 97980
- 61 + 97919 = 97980
- 97 + 97883 = 97980
- 101 + 97879 = 97980
Showing the first eight; more decompositions exist.
