Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82472, here are decompositions:
- 3 + 82469 = 82472
- 79 + 82393 = 82472
- 193 + 82279 = 82472
- 211 + 82261 = 82472
- 241 + 82231 = 82472
- 283 + 82189 = 82472
- 331 + 82141 = 82472
- 421 + 82051 = 82472
Showing the first eight; more decompositions exist.
