Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71290, here are decompositions:
- 3 + 71287 = 71290
- 29 + 71261 = 71290
- 41 + 71249 = 71290
- 53 + 71237 = 71290
- 137 + 71153 = 71290
- 251 + 71039 = 71290
- 293 + 70997 = 71290
- 311 + 70979 = 71290
Showing the first eight; more decompositions exist.
