Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162272, here are decompositions:
- 3 + 162269 = 162272
- 43 + 162229 = 162272
- 163 + 162109 = 162272
- 181 + 162091 = 162272
- 193 + 162079 = 162272
- 349 + 161923 = 162272
- 433 + 161839 = 162272
- 499 + 161773 = 162272
Showing the first eight; more decompositions exist.
