Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71488, here are decompositions:
- 5 + 71483 = 71488
- 17 + 71471 = 71488
- 59 + 71429 = 71488
- 89 + 71399 = 71488
- 101 + 71387 = 71488
- 149 + 71339 = 71488
- 227 + 71261 = 71488
- 239 + 71249 = 71488
Showing the first eight; more decompositions exist.
