Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71470, here are decompositions:
- 17 + 71453 = 71470
- 41 + 71429 = 71470
- 59 + 71411 = 71470
- 71 + 71399 = 71470
- 83 + 71387 = 71470
- 107 + 71363 = 71470
- 131 + 71339 = 71470
- 137 + 71333 = 71470
Showing the first eight; more decompositions exist.
