Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982128, here are decompositions:
- 11 + 982117 = 982128
- 29 + 982099 = 982128
- 31 + 982097 = 982128
- 41 + 982087 = 982128
- 61 + 982067 = 982128
- 67 + 982061 = 982128
- 71 + 982057 = 982128
- 107 + 982021 = 982128
Showing the first eight; more decompositions exist.
