Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84312, here are decompositions:
- 5 + 84307 = 84312
- 13 + 84299 = 84312
- 73 + 84239 = 84312
- 83 + 84229 = 84312
- 89 + 84223 = 84312
- 101 + 84211 = 84312
- 113 + 84199 = 84312
- 131 + 84181 = 84312
Showing the first eight; more decompositions exist.
