Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84980, here are decompositions:
- 3 + 84977 = 84980
- 13 + 84967 = 84980
- 19 + 84961 = 84980
- 61 + 84919 = 84980
- 67 + 84913 = 84980
- 109 + 84871 = 84980
- 193 + 84787 = 84980
- 229 + 84751 = 84980
Showing the first eight; more decompositions exist.
