Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71224, here are decompositions:
- 53 + 71171 = 71224
- 71 + 71153 = 71224
- 227 + 70997 = 71224
- 233 + 70991 = 71224
- 311 + 70913 = 71224
- 347 + 70877 = 71224
- 383 + 70841 = 71224
- 401 + 70823 = 71224
Showing the first eight; more decompositions exist.
