Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987252, here are decompositions:
- 41 + 987211 = 987252
- 43 + 987209 = 987252
- 53 + 987199 = 987252
- 59 + 987193 = 987252
- 61 + 987191 = 987252
- 109 + 987143 = 987252
- 151 + 987101 = 987252
- 163 + 987089 = 987252
Showing the first eight; more decompositions exist.
