Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84512, here are decompositions:
- 3 + 84509 = 84512
- 13 + 84499 = 84512
- 31 + 84481 = 84512
- 163 + 84349 = 84512
- 193 + 84319 = 84512
- 199 + 84313 = 84512
- 283 + 84229 = 84512
- 313 + 84199 = 84512
Showing the first eight; more decompositions exist.
