Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10212, here are decompositions:
- 19 + 10193 = 10212
- 31 + 10181 = 10212
- 43 + 10169 = 10212
- 53 + 10159 = 10212
- 61 + 10151 = 10212
- 71 + 10141 = 10212
- 73 + 10139 = 10212
- 79 + 10133 = 10212
Showing the first eight; more decompositions exist.
