Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71424, here are decompositions:
- 5 + 71419 = 71424
- 11 + 71413 = 71424
- 13 + 71411 = 71424
- 37 + 71387 = 71424
- 61 + 71363 = 71424
- 71 + 71353 = 71424
- 83 + 71341 = 71424
- 97 + 71327 = 71424
Showing the first eight; more decompositions exist.
