Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84222, here are decompositions:
- 11 + 84211 = 84222
- 23 + 84199 = 84222
- 31 + 84191 = 84222
- 41 + 84181 = 84222
- 43 + 84179 = 84222
- 59 + 84163 = 84222
- 79 + 84143 = 84222
- 101 + 84121 = 84222
Showing the first eight; more decompositions exist.
