Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84242, here are decompositions:
- 3 + 84239 = 84242
- 13 + 84229 = 84242
- 19 + 84223 = 84242
- 31 + 84211 = 84242
- 43 + 84199 = 84242
- 61 + 84181 = 84242
- 79 + 84163 = 84242
- 181 + 84061 = 84242
Showing the first eight; more decompositions exist.
