Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71430, here are decompositions:
- 11 + 71419 = 71430
- 17 + 71413 = 71430
- 19 + 71411 = 71430
- 31 + 71399 = 71430
- 41 + 71389 = 71430
- 43 + 71387 = 71430
- 67 + 71363 = 71430
- 71 + 71359 = 71430
Showing the first eight; more decompositions exist.
