Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177222, here are decompositions:
- 5 + 177217 = 177222
- 11 + 177211 = 177222
- 13 + 177209 = 177222
- 109 + 177113 = 177222
- 113 + 177109 = 177222
- 131 + 177091 = 177222
- 179 + 177043 = 177222
- 211 + 177011 = 177222
Showing the first eight; more decompositions exist.
