Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71506, here are decompositions:
- 3 + 71503 = 71506
- 23 + 71483 = 71506
- 53 + 71453 = 71506
- 107 + 71399 = 71506
- 167 + 71339 = 71506
- 173 + 71333 = 71506
- 179 + 71327 = 71506
- 257 + 71249 = 71506
Showing the first eight; more decompositions exist.
